A Trip Down Computer Memory Lane
News.com has an interesting stroll down memory lane with a look at the "DigiBarn", a collection of technology from early mechanical calculators to modern web appliances. NASA contractor Bruce Damer and partner Alan Lundell run this "museum in transition" from a 19th-century farmhouse deep in the Santa Cruz mountains. In addition to notable success milestones, the company also includes some of the industry failures, like an Apple III Damer acquired from Apple's legal department.
Could be called RAM Drive, but Computer Memory Lane is cool too

Go on. Read the article. You know you want to. You'll find out why the museum has to be packed up every winter, and learn that Apple had a portable music player as far back as 1979. And more!
This article is crap.
The link goes to page 2 of the article.
I'd be interested to learn more about the "iPod prototype" - described as a Mac in a briefcase - how was the music stored on this? If it were on separate medium such as cassette, disk or somesuch then is it really a prototype of anything? Would it not be a similar, more cumbersome version of the Walkman, which had already appeared by 1980. Since it's a Mac I'd like to say the files were in AIFF format, 'cept WP says that was developed in 1988. What was the state of audio compression at the turn of the eighties? Uncompressed audio seems unrealistic on yesterday's storage media.
The article says:
I remember needing just a putty knife and a foot-long Torx wrench (the screws that held it together were seated at the top of the machine, but only accessible through deep holes in the bottom)....

For the SE and Plus and probably some others, you needed the "Mac Cracker" in addition to the long T-15. The cracker was a spring loaded device that pushed parts of the case outward in order to open it.
...that this is a just another computer museum, rather than one dedicated to computer memory, I was getting excited by the thought of all those glass cases full of SIMMs, DIMMs and maybe even some magnetic core.
ccalam - acoustic versions of new songs.
Is it that hard to put a link to the actual museum instead of to page 2 of an article that talks about said museum? Are the mods asleep today?
today is spelling optional day.
the article forgot Amiga....
Ah the irony, a computer museum filled with old M$ OS. Bill Gates once boasted that he would keep a copy of gnu/linux for his computer museum but would eliminate it otherwise. Yet nothing is more useless than an old copy of Windoze. They can be fun, but they are tied to a particular set of hardware and software that's all rotting away. Emulation is interesting but difficult thanks to all the built in traps. Still, it's nice someone is keeping these things around.
Roughly Drafted has a set of articles detailing the OS wars that would complement the physical collection. If you are looking for a trip down memory lane, here it is:
They are all well written, entertaining and accurate.
Friends don't help friends install M$ junk.
I remember when I got my 1st Radio Shack Model 1. I remember when I bought a Kaypro II. ( I still have it ). I remember how much I loved writing Z80 Assembler on CP/M.
I started out fooling around with these computers, sharing information on CP/M bulletin boards, learning how computers worked from the ground up.
I also remember having the opportunity to meet industry leaders like George Morrow, and work for Takioshi Shiina of SORD computer of Japan. I got to travel, and live in Japan working for SORD.
I remember COMDEX when there were competing operating systems and unique hardware before Microsoft got a strangle hold on innovation and creative thinking.
I remember a time where software patents were unheard of and the thought that ideas for software not the software itself could be owned by some one.
I think of how lucky I have been being able to work on projects where the ideas of creative people not the lawyers and accountants counted the most.
I have been lucky to have grown up in that time.
Thank you Mr Shiina
Cheers

A few emulators can read from WAV files of the tapes. MP3 should be okay bandwidth-wise, but the psycho-acoustic model throws away information humans can't hear, and I don't know if that is a problem for some data encodings. The WAV-reading only exists to load files from old tapes, it's not a sensible long-term storage mechanism.

Anyway, the tape->MP3 conversion seems like a common sense idea, but a quick search didn't turn up anything.
Back in the mid-90s, before mp3s became popular, a small company did a limited run of audio CDs that contained most/all of the games for the Starpath Supercharger Atari 2600 add-on.

I did this myself a few times even before, but by actually installing the OS on older boxes. Either way, the "Windoze" copies are handy to keep around.
What does this even mean? You mean Linux 1.08 x86 isn't tied to some hardware that's "rotting away"?
How is it "difficult" and what are the "traps"? So far VPC and VMWare work fine for most people.

With a little knowledge of the tape hardware and the way it's used to store data, you can store the data on a tape much more efficiently than an MP3 does (and get faster encoding and decoding to boot). Your average 8-bit with a tape deck (for example, a ZX Spectrum) essentially has a 1-bit ADC and DAC hooked up to the tape deck. Data is (mostly) stored on tape as a long series of pulses of two different lengths (each representing a 0 or 1). Therefore, to create a nice and small tape image file (even of data in a custom copy protected format), simply detect and store a description of these pulses in e.g. TZX format. Especially Spectrum emulation users often work with tape files like these.
We have - certainly in the Sinclair Spectrum community. Nearly every piece of Spectrum software has been saved. Not in MP3 format, but in TZX format which gives a compact and accurate representation of the original tape. The World of Spectrum archive has several thousand programs for the Speccy stored in this way.

Thats why none of our prototypes ever got off the ground. Storage meida was just to expensive and compression was limited.

They should take some of the crap in my garage. My retirement investment. You never know when someone might want a Type 80 rectifier, CK722s, BC-348, RTL chips, JSR Model 15, 1401 core memory, bubble memory, 8080, etc... Not mention the magazines / books, LOTS of books. My wife loves it. Not...
MP3 compression is lossy. You do not like audio drop outs on tape, you would not like the non-sense result of MP3-compressing a program saved to audio tape. I am not even sure the loss-less audio encoders would cut it. They are designed for a digital audio input (generally CD quality audio or below), not the A/D conversion back up format on circa 1980s audio cassette tapes.
I remember not too long ago when hard drive prices were high enough people were dreaming up ways to back up their data to the video micro-cassette tapes used in consumer camcorders.
In the bad old days, there was a key difference between PC-DOS and MS-DOS. PC-DOS was useless for clone machines if the user wanted to program in BASIC. At the time, IBM was putting the BASIC interpreter on chip, there as a basic.com file that would call up the interpreter. MS-DOS was distributed with BASIC and then later GW-BASIC, and finally QBASIC. I think IBM stopped with the BASIC ROMS when the XT came out.
Politics is the art of looking for trouble, finding it everywhere, diagnosing it incorrectly and applying the wrong fix.
The article states that the IBM PC was an open architecture. In fact it wasn't.
Whilst the OS, CPU, RAM, UARTs, DMAs etc could all be purchased from 3rd parties (Intel, Microsoft, Motorola and friends) they were not open in the OSS sense, the BIOS was proprietory. Compaq then Phoenix had to write clean room BIOS's to make a compatible machine. The same is true of the video BIOS.
Time flies like an arrow. Fruit flies like a banana.
Back in the day, with the Scalectrix that I had, I had a couple of circular "mechanical computers" that looked alarmingly like that navigational aid from TFA. They were speed calculators, from what I remember, but they were simply a circular slide rule, of sorts.

Ahh, but do you have a wire recorder? :)
Mine is actually a cassette recorder. OK, the cassette is about 5 pounds, but . . .
[explanation: A WWII or earlier vintage machine, it recorded autdio on spools of wire. The specimen I have uses a cartridge, about three inches tall and deep, 8-12 wide (I'm not going out to check), with spools. I actually have a (broken) second spare cartridge. Some day I'll get the whole thing working.]

At least on a ZX Spectrum, the psycho-acoustic models do damage the data enough to make it impossible to load. I exported a few .TZX files into .WAV, compressed them into MP3 and tried to load into my 48k Spectrum from a portable MP3 player. I didn't manage to load the program one single time as every attempt ended with an "R Tape load error". I also tried recording the .WAV onto a minidisc (old MZ-R90 portable) but still got similar results, so apparently ATRAC loses too much data as well. Burning the .WAV files onto CD as audio tracks worked flawlessly, though.
I really dont know why do article come out pointing to an half baked computer museum,check this one out , http://www.homecomputer.de/ , and tell me wich one should be on the news ! Jorge Retro Review Magazine http://www.retroreview.com/
>old tapes to MP3s
For some strange reason, lossy compression is something you *really* don't want with program/data files.

You see a lot of old hulks there- a fascinating excursion down memory lane. The museum is located in an old SGI building, slowly being engulfed by the Google Ameoba up the road.
Here are some videos I took of the digibarn last fall. Unfortunatly, my camera malfunctioned when I tried to take more videos during Bruce's most recent tour.
No, I will not work for your startup
There are also methods for transferring files over audio connections between vintage and modern hardware. ADTPro works with the cassette ports in an Apple IIe, II+, or II. I remember reading recently about something with similar capabilities for the TI-99/4A, but I don't recall the name offhand. (Some quick looking-around turned up Tape994a and CS1er.)
With most computers writing to tape at somewhere between 600 and 2400 bps, I'd think that lossless compression would be able to shrink the file size significantly without running the risk of garbling the data.

Towards the Singularity.
There are more than one advantages to taking the cleanroom approach.
It was open for most practical purposes until Microsoft was able to wield a long enough but to close it down.
Personally, I don't really care if he said it or not, it was what DOS said.
I remember the hours of pain using 3rd party loaders that could access RAM above 640KB while trying to reduce the number of programs that use the sacred first 640KB of RAM.
Same way I wouldn't care if Jobs said "1 mouse button should be enough for anyone". It's still implied. (hopefully this doesn't start a mouse button tangent, but you get the idea).
It's turtles all the way down.
