Previously Unknown Warhol Works Recovered From '80s Amiga Disks

First time accepted submitter mooterSkooter (1132489) writes "Magnetic Imaging tools were used to recover a dozen images produced by Andy Warhol on his Amiga computer. I would've just stuck the disks in and tried to copy it myself." Read more about it from the Frank Ratchye Studio for Creative Inquiry, which says "The impetus for the investigation came when [artist Cory] Arcangel, a self-described “Warhol fanatic and lifelong computer nerd,” learned about Warhol’s Amiga experiments from the YouTube video of the 1985 Commodore Amiga product launch. Acting on a hunch, and with the support of CMOA curator Tina Kukielski, Arcangel approached the AWM in December 2011 regarding the possibility of restoring the Amiga hardware in the museum’s possession, and cataloging any files on its associated diskettes. In April 2012, he contacted Golan Levin, a CMU art professor and director of the FRSCI, a laboratory that supports “atypical, anti-disciplinary and inter-institutional” arts research. Offering a grant to support the investigation, Levin connected Cory with the CMU Computer Club, a student organization that had gained renown for its expertise in “retrocomputing,” or the restoration of vintage computers."

Re:1985

They introduced a new feature in 2015 that allows broadcasts to be sent back in time.

However, due to a lightning strike, it got stuck on 1885 after sending only a few videos back to 1955.

Amiga Floppies

[tekrat]

They could have just used the disk drive. 99% of my Amiga floppies still work just fine.

The Amiga 1000 was a surprisingly durable machine, and frankly, Commodore, despite anything you could say about them making "toy" computers at a target price used very high quality components.

A modern PC's power supply will burn out long before a 25-yr old Commodore power supply will.

Re:Amiga Floppies

[Kl00dge]

You apparently never had to put your C64 power supply in the refrigerator.

Re:Amiga Floppies

[mooterSkooter]

Exactly what I thought. I would have just tried the disk in an Amiga with a HD attached, made an image and copied that over to try out in an emulator. Magnetic Imaging devices indeed! Well, makes for a more interesting story I suppose.

Re:Amiga Floppies

[Rob the Bold]

You apparently never had to put your C64 power supply in the refrigerator.

I've heard of drilling through the potting material to remove and replace a fuse buried in there, but never that. What was the hope behind the refrigeration of the "brick"?

Re:Amiga Floppies

[bws111]

I hope your not an archeologist or forensics expert. The first thing to be concerned about, when dealing with a one-of-a-kind artifact, is to minimize any POSSIBLE (not probable) damage. There is a non-zero probability that using a disk drive could cause damage. There is less of a possibility that magnetic imaging would cause damage.

Re:Amiga Floppies

[Kl00dge]

It was farily common, at least among people I knew, for the power supplies to overheat. I believe it was the early units. It would just shut down and we'd stick them in the refrigerator or freezer for a few minutes so we could get another 45 minutes or so out of them.

Re:Amiga Floppies

[Charliemopps]

ALL computers in the 80s were built like that. To this day, I still have an IBM keyboard from the early 80s that I'm pretty sure I could hammer nails with.

Re:Amiga Floppies

[qwijibo]

Of course you could still hammer nails with it, but can you plug it in and *type* on it?

I used to know people who would carefully disassemble their old IBM keyboards, run the parts through a dishwasher and reassemble them, fully functional.

These days, I'm not sure if some keyboards could stand up to the compressed air in a can cleaning.

Re:Amiga Floppies

[jrumney]

False, and false. I have toasted many an Amiga power supply, and a number of Amiga chips.

Ditto, by playing around with the parallel port. There were no buffer ICs on the old Amigas to stop bad things happening to the main processor or coprocessors when there were shorts on the external I/O pins.

Re:Amiga Floppies

[timeOday]

My (parents') Amiga 500 died half a dozen times from electrostatic discharge. Ultimately we made a mat to sit it on, out of cardboard wrapped in foil and wired to the wall outlet ground. You would spark yourself on the mat before using the computer.

Re:Amiga Floppies

[Misagon]

99% of the Amiga floppies I still have work fine, but back in the day, I had to throw away 99% of my floppies quite early because of read/write errors.

Re:Amiga Floppies

[JMZero]

We just put a fan on ours, and it stayed up. But yeah, the power supply was the only thing Commodore hardware I ever heard of problems with.

Re:Amiga Floppies

[DerekLyons]

A modern PC's power supply will burn out long before a 25-yr old Commodore power supply will.

Nonsense. Back in the early 90's I sold consumer electronics for a living, and we did a brisk business in aftermarket and grey market power supplies for various Commodore machines - because the stock power supplies burned out with depressing regularity and stock replacements were expensive and difficult-to-impossible to obtain from official sources.

Re:Amiga Floppies

[Sipper]

I've heard of drilling through the potting material to remove and replace a fuse buried in there, but never that. What was the hope behind the refrigeration of the "brick"?

Yes, the C64 power supply was potted -- and after digging through it what had to be replaced wasn't a fuse, it was a 5v linear regulator. The problem with the C64 power supply was that the Linear regulator was designed for 1A, but Commodore was using it to pass 1.2A. This shortened the life of the part, and when it failed it required a huge effort to dig through it to find the part that was bad and replace it.

But I did exactly that. And unfortunately one generally had to do that if they wanted to end up with a reliable supply, because the replacement supplies had the same design flaw and would thus fail in the same way. Once I replaced the 5v regulator with one that was rated for 1.5A, it never failed again. :-)

Re:Amiga Floppies

[Sipper]

You apparently never had to put your C64 power supply in the refrigerator.

The C64 power supply used a 5v linear regulator rated for 0.2A - 0.3A less current than the C64 itself drew through it, so the part would have premature failure because it was underrated. Apparently/supposedly the difference was expected to be dumped as heat, and the supply was potted which made it very difficult to get to the part that failed and replace it... but doing so was necessary because the replacement supplies had the same design flaw. I did that replacement and after doing so the power supply looked terrible (I left it ripped open), but with a linear regulator that had a sufficient current rating it never failed again (whereas the replacement supplies all did).

Putting the power supply in a refrigerator sounds terrible (but dedicated), but then, so was the "correct" fix. ;-)

Re:Amiga Floppies

[Retron]

22 years ago I was given my first PC - one which my dad's works had thrown out. An original IBM PC, complete with dual floppies and a mono screen (and cassette port around the back). Sadly it was thrown out a couple of years later when we upgraded to a 486, but I kept the keyboard... an IBM Model F which is built like a tank. It can still, in theory, be used with a modern PC if you use a signal converter... which costs a small fortune. Not that I'd want to, though, as the keys are in odd positions (eg control is where caps lock now is).

I'm typing this on an early 90s Model M keyboard which I bought from eBay many years ago. It connects via a PS/2 port and seems indestructible, albeit not quite as nice to type on as that Model F was. It's quieter than the F though, which is handy. The Model M was available back in 1984... hmm, 30 years ago this year!

Side note: due to spending far too much time on that PC as a 12-year-old, I ended up using the numeric keypad for cursor control. It's a hard habit to kick, as I do the same over 20 years later - I very seldom have numlock on, instead using the numbers above the letters for numeric data entry.

Re:Amiga Floppies

[idontgno]

Of course you could still hammer nails with it, but can you plug it in and *type* on it?

If it's one of the classic Model "M"s, you could type by hammering nails with it, if you're skilled enough to strike the nailhead with the specific keys you want.

Nowadays. Feh. I have given up on decent keyboards. I will settle for less violently sucky ones. And have to look pretty far afield to fine one.

Re:Amiga Floppies

[idontgno]

Proof-positive that Darwin was right. Natural selection yielded a subset of the species with strong survival characteristics, while winnowing out the weak.

Yeah, even today, I'm terribly surprised and disappointed if any of my Amiga floppies fail while I'm reading them. I suppose I should hurry up and copy them onto a hard drive as image files before something I care about dies.

Re:Amiga Floppies

[amigabill]

I'm curious about how they do magnetic imaging without running it across a floppy drive head. Is there yet any detailed infomration about how they accomplished their magnetic images? Or in general how it's done, whether or not if that was their process?

Re:Amiga Floppies

[pjt33]

By the Amiga 500 they'd improved. All I had to do was put a rubber hot water bottle (filled with cold water) on the power supply to act as a heat sink.

Re:Amiga Floppies

[Darinbob]

Two problems, first they didn't want to damage the disks, and second the .pic format is pretty rare (and not well supported even in early Amiga days).

Re:Amiga Floppies

[Darinbob]

Those are rare though and hard to find, probably full of dust, and not the sort of thing you want to stick a valuable floppy disk in. (those artists who examine Warhol's work are very careful and treat it all like something amazingly precious, even his old underwear, which I am not making up)

Re:Amiga Floppies

[Darinbob]

Control is SUPPOSED to be where the capslock is now, it was the universal standard! The idiot that changed the position is still in hiding in the witness protection program!

Re:Amiga Floppies

[amigabill]

Also, if they did much research, they might have found that one of the few remaining Amiga hardware peripheral producers has for some time sold floppy disk controllers that I understand are popular with Forensics people, as they can read a very wide variety of formats on a standard PC.

Certainly you're not talking about the C=64 power supplies that were notorious for burning out after only about a year of moderate use?

Re:Amiga Floppies

[AK Marc]

Floppy reading is a destructive process. In a healthy disk, the disk will not be damaged by it. But you could have a disk with the information on it, but not durable enough to be read with a standard disk drive.

Re:Amiga Floppies

[sjames]

Same here. A bigger regulator with a proper heat sink solved the problem for good. It didn't help that the original heatsink was embedded in the epoxy.

Re:Amiga Floppies

[sjames]

If the data is irreplaceable and potentially valuable, magnetic imaging is safer than running the disk through an old drive. So, retrieve MY doodles using an old drive, use imaging for Warhol's.

Re:Amiga Floppies

[Bing Tsher E]

True, but people will pay stupid massive amounts of money for his stuff. So in the sheer spirit of commercialism it's prudent, and profitable to humor the Warhol fans, to reap the highest profit from them. Andy certainly did this and we should too, in memory of him.

The Amiga and its demo scene were more art than Warhol ever will be.

Re:Plastic "art"

[CastrTroy]

From looking at the "art" it looks to have little artistic value. Warhol didn't have any particular skills in computer art, and the software was quite limited in what you could do at that time. It's nothing that anybody else messing around with the same program couldn't have produced. Just because Warhol is a notable artist, does not mean that every piece of art he produced is worthy of our attention. Some people are great authors, but that doesn't mean their shopping lists or twitter posts, are literary works to be cherished.

But a Warhol is valuable, Art is in the eye of the beholder. Some people apparently think giant soup cans are works of genius. No accounting for taste.

Re:Plastic "art"

[Anonymous Coward]

Pretty much.

There is a reason Warhol decided not to release those images. Saying that this is something other than just a bit of fooling around to learn the tool is an insult.

While not the same situation this reminds me of people trying to analyze literature. If the writer would have intended for you to interpret the text differently he would have rephrased it. To say that the text needs interpretation is equivalent to claiming that the writer was too incompetent to get his message across.

I wish I had mod points.. but you are dead on, the demo scene was where talent lied, and just look at these 'wharholian' pieces. a copy/pasted eye, the campbell soup can (one hit wonder) done by a drunken 3yr old, and some pasted video capture of him reading the instructions. yawn.

So, you hold a PhD in art history? Or have you ever taken a single entry level art history class?

Re:Plastic "art"

[HornWumpus]

Warhol's 'art' isn't old enough to have passed the test of time.

Art history records many examples of things that were art at the time but are now recognized as junk. Art history is not the same subject as art. It actually includes looking at trends that are stupid in hindsight. Like pop art and photo real paintings.

Re:Plastic "art"

[Sentrion]

Do you have any idea how many scholars and academics earn their living writing literature and creating works of art for the sole purpose of having other scholars and academics review, critique, and interpret their work, all while getting paid to sell textbooks that they write, and paid to tell students how important those works are to read and study?

By pointing out the lunacy of this system you are endangering an entire sub-culture and way of life. They could have you burned at the stake as a heretic.

Except for the tiny fact that art is wholly subjective and quantum physics is wholly objective, sure.

Re:Plastic "art"

[517714]

Warhol was mostly marketing, like Kim Kardashian with a paint brush.

But you challenged us to read, so from Wikipedia:

"New York's Museum of Modern Art hosted a Symposium on pop art in December 1962 during which artists like Warhol were attacked for "capitulating" to consumerism. Critics were scandalized by Warhol's open embrace of market culture."

"In 1979, reviewers disliked his exhibits of portraits of 1970s personalities and celebrities, calling them superficial, facile and commercial, with no depth or indication of the significance of the subjects. They also criticized his 1980 exhibit of 10 portraits at the Jewish Museum in New York, entitled Jewish Geniuses, which Warhol-who was uninterested in Judaism and Jews-had described in his diary as "They're going to sell."

"The Philosophy of Andy Warhol (1975), 'Making money is art, and working is art and good business is the best art.' "

I believer it is the opinions of those critics and reviewers which have stood the test of time, not Warhol's artistic works.

Re:Plastic "art"

[mcgrew]

Critics that were contemporaries with the likes of Manet, Van Gogh, and Gaugan were similarly shunned by the establishment. Meanwhile, paintings that hung in galleries and were critically praised at the time are worthless today.

If it evokes an emotional reaction, even if that reaction is contempt, it's art. The worst insult you can hurl at a painter is "gee, that's pretty."

Re:Plastic "art"

[mcgrew]

Art is man-made and its scholars fully understand it. That's not the case with quantum physics, yet at least.

Re:Plastic "art"

[mcgrew]

In a subject that is not my field, I have little choice but to listen to those who have studied in the field.

Re:Plastic "art"

[mcgrew]

You can start with the dictionary.

Re:Plastic "art"

[mcgrew]

Art history records many examples of things that were art at the time but are now recognized as junk.

Entirely true. Van Gogh was a failure who couldn't sell paintings. Gaugan and Manet were panned by contemporary critics, while the works that were critically praised and hung in expensive galleries are worthless today.

Warhol has been dead for a quarter of a century. Maybe enough time has passed, maybe not. But these guys who have never had an art history class who think they know what art is are ludicrous.

It actually includes looking at trends that are stupid in hindsight. Like pop art and photo real paintings.

Have you ever seen an Audrey Flack painting in a museum? Photorealistic still lifes that will take your breath away.

Re:Plastic "art"

[TangoMargarine]

Are we talking about "fully understanding" the *history* of the piece of art, or the artwork itself? Because I can know who painted something, what materials they used, where and when they painted it, but still know nothing about the meaning of the art.

Plus, if you just *ask* the creator what his art means, maybe they'll tell you. In which case, how can we really be said to be "studying" anything? If we had an oracle that just told us how quantum physics works, we wouldn't really need to study that either.

But maybe it's just because I don't understand the idea of e.g. close reading, as an engineerish person. If we have to ask the artist what their art means, that seems to kind of defeat the whole point. And you'll get teachers who interpret books to mean things that the author never meant, based on the prevailing social trends of the time.

A truly attentive close reading of a two-hundred-word poem might be thousands of words long without exhausting the possibilities for observation and insight. To take an even more extreme example, Jacques Derrida's essay Ulysses Gramophone, which J. Hillis Miller describes as a "hyperbolic, extravagant... explosion" of the technique of close reading, devotes more than eighty pages to an interpretation of the word "yes" in James Joyce's modernist novel Ulysses.

Re:Plastic "art"

[mcgrew]

Are we talking about "fully understanding" the *history* of the piece of art, or the artwork itself?

The artwork itself. The composition, use of color, symbolism, etc. The history only points to where a work stands in relation to works before, contemporary, and afterword.

It was an interesting class. Not very useful, but interesting.

Re:Editorializing

[Dahan]

Most serious software archivists would simply plop the disks in a floppy drive connected to a Kryoflux, or similar device, and be done with it.

And that's exactly what they did. They imaged the floppies with KryoFlux connected to a known-good, clean, Amiga floppy drive. TFA has a link to the technical details.

Re:Editorializing

[Dahan]

Of course a 3.5" floppy drive can damage a disk. The head is in contact with moving media. Should it damage the disk? No. CAN it damage the disk? Certainly.

Which is why they cleaned the floppy drive before putting the disks into it. "The primary concern was damage to the disks during the reading process. While impossible to eliminate without using extremely expensive equipment well beyond the reach of involved parties, it was believed this risk could be minimized by using a recently cleaned and tested floppy drive for copying ..." -- from the report detailing what they did.

Not sure why there seems to be this assumption that because they made an "image" of the disks, they must not have used a regular Amiga floppy drive. These days I often make images of hard drives... I don't take the platters out in a clean room and use some special microscope to do it. I plug in the drive as normal and use software. Similarly, they imaged the floppies by using a regular Amiga floppy drive, albeit connected to a fancier floppy controller card that can even image disks that may have errors.

Re:Editorializing

[Chordonblue]

Ever seen the metallic material completely stripped off of the plastic of the disk? I have. Some companies were better than others are producing quality disks - who knows what might have happened otherwise? Better not to take the chance of damaging something not restorable and doing it the hard way rather than the easy and quick method.

Re:Editorializing

[linebackn]

And that is why, like I said, you attach your floppy drive to a Kryoflux, SuperCard Pro, or Deluxe Option Board device.

Re:Editorializing

Mod parent up. TFA made it sound like they did raw complex magnetic imaging similar to that Cray disk that was recovered while back.

Compared to that, using a Kryoflux is little more than "throwing it in a floppy drive".

You've just found an undiscovered work by Andy Warhol. Do you want to:

2. Call an appropriate professional for advice?

Because I'm pretty sure that . . . "I would've just stuck the disks in and tried to copy it myself" . . . is the physical artifact equivalent of using some randomly chosen household cleaner. And museum curators are pretty anal about curation of their stuff.

Also, for the love of God, do not use "DiskDoctor"!

Re:What not to do

Let me see... I last used a floppy a couple years ago and it was basically single-use: wrote data to it once, got it back off once, then Bad Sector City. Most of that 10-pack of floppies was the same way.

I understand they wouldn't use it in this case but I always used Disksalv. Looks like it is still being maintained and is now freeware.

Poser! They never made the Amiga in any color than dead-fish beige! (Except for the CDTV and CD32, which were "A/V component charcoal".)

Hell, does any computer come in a primary color, other than overaggressive "compensating for something" red on certain gaming-grade systems?

And yes, I'm joking, and I know you don't mean color when you say "mint".

I'm just trying to forestall the inevitable "whoosh" here. Even if it kills the joke.

Mint was the flavor of the computer you berk!

Reverse engineer the format???

[LWATCDR]

Odds are very high that they where IFF. Commodore created a universal documented format container called IFF back in the day. The Graphics version was completely documented and is evens still supported by a lot of graphics programs.

It was said in the BBC article emulators couldn't load it, and considering GIMP loads IFF, and he had a pre-release Amiga 1000 with unreleased software, it's entirely possible it was from before the Interchange File Format was standardized.

Sure enough, turns out to be the case, paraphrased from the PDF linked above, An older format deprecated by 1990 was called PLBM (PLanar BitMap, compared to the ILBM interleaved bitmaps you might recall as typical IFF). This format is much more poorly (sic) documented. One disk contained an EA slidshow of PLBM files. A pre-release version of Graphicraft, as well as the A-squared framegrabber both produced what they dubbed a "Graphicraft format", essentially an uncompressed PLBM without an IFF header. All the files found in that format contained at most 32 colors.

Per those commenting on robustness, 40 disks, 4 had bad sectors, 9 had file system issues. Half of those impacted files/used space.

No - Warhol started doing Amiga art before IFF. The first Amiga graphics program was Graphicraft and the .ILBM IFF format hadn't been created yet. IFF was used for all subsequent Amiga art programs. Somewhere I actually have a Warhol-signed floppy from the launch with Warhol's Debbie Harry pic on it. I believe at some point I did convert the Graphicraft file to ILBM (I may have written a converter myself a long time ago). I also got to visit Warhol's studio once with another Commodore employee to fix the color printer attached to his Amiga. Back then personal color printers were very new, big and very messy to clean the jets and replace the inks. Warhol was not in the office when we fixed it.

"According to that document, they were only loadable with a pre-release Kickstart found on one of the disks (the Amiga 1000 booted an early BIOS from ROM and then loaded the Kickstart from disk). Evidently they changed the format before the commercial release."
That makes no sense at all. The OS did not have a picture viewer or OS calls to load images from disk. Kickstart was basically just the ROM part of the OS. When launched AmigaOS was not stable enough to put in rom so Commodore stuck in a writeable control store. After Kickstart you had to boot the Amiga with the Amiga OS disk. In other words none of this makes any sense at all unless the disk format was different than the release version.

I had an Amiga 1000 and used Kickstart 1.0. I bought one at launch and the IFF format was fully documented by then. IFF might have started with EA but the IFF container was expanded to work with just about all datatypes.
Simple truth is that "reverse engineering" graphics formats from that period on the Amiga is really simple. You knew it was one of a few resolutions and one of a few depths. If it was HAM you might have had a bit of an issue but HAM based paint programs were not yet common or frankly available. Compression was rare because of the time it took to decompress files when loading them into paint programs.

I've had the pleasure of working with the CMU CC for the past several years, broadcasting their Demoparty, Demosplash, on Scenesat the past several years. These guys are seriously passionate about retrocomputing and The Demoscene. They have released some neat Demos for the Apple Lisa and the Vectrex. Good to see them getting some recognition here. They're nice bunch of guys, and the Warhol museum certainly picked the right people for the job, right in Pittsburgh.

If you're in the Retro computers and the Amiga, they showcase a TON of it at Demosplash, both by allowing you to play games on them and by showcasing Demos, so its worth a trip.

uh..really?

That Venus is not the work of Andy Warhol if I remember correctly. (Well, he might have done the HAM-fisted cut and paste of the third eye in the middle of her forehead..)

I remember seeing it on the cover of one of the Amiga magazines as the full reproduction. I realize that Warhol stole most of what he did from other artists, but surely this has to be a joke.

Re:uh..really?

There's the original. I was wrong, it wasn't a full reproduction - but it was a Deluxe Paint marketing image for sure.

Are you sure?

[Tablizer]

When you only have 16 colors, everything looks like a Warhol work.

Re:Are you sure?

[Anonymous Coward]

16 colors at 640 horizontal resolution. At 320 you can use 32, 64 Half-Brite (32 colors with an additional 32 at 50% intensity), or HAM color modes.

Re:Are you sure?

[Tablizer]

It was mostly meant as a joke; a poke at Warhol's style.

Wow, that was a lot of trouble to go through...

[aflyingcat]

Seriously ? They could have just asked. They didn't have to go to all that trouble to recover the images. Not only were there backup disks made at the time, but the images were converted and stored as IFF files after the Amiga's launch. I know a few ex-Commodore people who have signed backup disks from Warhol from the training sessions for Warhol, and from the launch itself. The graphics program he used at the launch was an early beta version. It had a more than a few bugs. Area fill in particular was a problem. Before we launch , we went over with him about what not to do during the launch demo. And of course, he completely forgot during the presentation, and went right for that button. Our rows went entirely silent when he hit that button :-) It was a major relief when the program did the fill and survived. There was a plan B, fortunately, it was unnecessary.

This is why the Amiga Demo Scene was so amazing.

(Other brands had good demo scenes as well. The Amiga just had the best graphics capability of anything you could purchase at that time.)

Re:Art and programming

[jrumney]

A lot of these are from later models, with 24 bit support and higher resolutions. The original Amiga supported only a 64 colour palette from a total 4096 colours, and an additional feature where you could modify the palette part way through scanning to get smooth gradients, but techniques for exploiting this would not have been refined at the time of launch of the Amiga 1000.

Demos that used the Ham modes only did it for static pictures, all the moving parts (which was usually why you watched demos, other then to listen to the music) was done in the normal Amiga modes. So that was usually 32 (OCS) colors to 256 (AGA).

While there can be exceptions, that is generally how the Amiga Demo's are. They were also about pushing the hardware past it's limitations, so if you know of any demos that do higher then 256 colors, let me know so I can check them out.

Re:my image is floppy

[stderr_dk]

images woulda been bitmap and not vector so wouldn't exactly move up to png

Why not?

The images would most likely be in IFF ILBM format. ilbmtoppm can convert those without any problems.

If you want a png, just add a little pnmtopng and you're done.
