Hand-made Web Server, Built From 200 TTL Chips

And as part of its stress-testing procedure, its been slashdotted!
This just goes to show the kind of amazing innovation that can still come out of a garage project. One guy working on his own can sometimes come up with ideas that the big guys like Intel etc are just too slow to be able to jump on. They're all fiddling around trying to get their buggy Verilog tools to work, while this guy just goes and wire wraps it in a few evenings. Bravo! I'll bet it takes the big semiconductor companies at least a year to catch up with this.
He posted his 3 Mhz server on slashdot.. i guess that by now that fine wire-mess is a melted wire-mess...

A musty atmosphere of neglect pervaded the subbasement of University Library. The books on the shelves were covered in a fine layering of dust. There were dim lights over the small study cubicles at the end of each aisle between the towering shelves. The lights produced only enough illumination for the top of the desks, leaving the surrounding stacks and central walkway shrouded in a perpetual twilight.
I had finally found the copy of the heavy API guide I needed for my work connecting my SQL database to the graphical front end I had been slaving over all weekend. However, the intricacy of the cover of the neighboring book drew my attention and I brought it along to the desk for better inspection under the light. The cover looked a lot newer than the heavily thumbed volumes beside it. Emblazened
across the front was the title "Linux - Unleash the Power of your PC" together with a picture of a fat cartoonish looking penguin. As I opened the book I felt a strange buzzing in my head that quickly passed. I shrugged it off as my attention was drawn to a CD which dropped out and landed on the desk in front of me. It bore the same title as the book, together with something about 'Knoppix' which was a word I did not recognise.
I had heard of Linux though. The University ran Unix on some of their servers, although I rarely chose to interact with those systems. Perhaps I should broaden my horizons though. I liked to think I knew just about everything there was to know about using Windows, but you could never have too many strings to your bow. Almost without thinking I slipped the CD into my pocket and returned my attention to my work.
A date with my girlfriend Paige followed the work in the library. I was one of the few students on my CS course to actually have a partner since, although computers interested me and would one day be my means of making a living, I was careful not to get drawn into the geek subculture that seemed to pervade the department. Some of the guys with their nerdish glasses and unwashed t-shirts grunted at me strangely when I declined to join in their games of Counterstrike, but I reminded myself that while they were shut up in a grimy computer lab scoffing Cheetos I was getting laid on a regular basis.
That night in my dorm room while I was getting ready for bed, I remembered the CD in my pocket and fired up my laptop to take a look. I still couldn't make out what the strange messages flowing across the screen meant. Perhaps if I sounded them out their meaning would become clear. I tried to phonetically pronounce the words but they disappeared too quickly to be replaced with a blank screen. I gave up, turned off the light and climbed into bed.
The erotic dream started with Paige slowly caressing my back and buttocks. The caressing transitioned into an incredibly gentle massage starting at my neck and shoulders and running down my back. My butt cheeks were being massaged apart and I spread my legs and raised my rear as her hand reached underneath me from behind to stroke my erection. Her hand was very warm and felt wonderful as I started to slowly thrust into her hand as she started jerking me off. A huge long warm and moist tongue started playing over my testicles and anus. It felt fantastic. No one had ever licked me there before. I never knew how sensual it felt.
As her hot hand was expertly running up and down my rigid penis something started probing my anus. It snaked its way into my anal opening and it started slowly expanding. Suddenly I had the urge to move my bowels, but I didn't care, as my attention was totally focused on my imminent orgasm. My penis was released as Paige suddenly grabbed my sides and jammed her hips against my butt.
I woke up to find myself with my rear in the air. Someone was grabbing my sides and hitting my butt. I jolted fully awake as I felt something expanding in my rectum and realized I was being fucked. The cock in my butt was still expanding and was becoming painfully large. I thought I could actually feel it movin

Dvorac first to break the news that Apple will be switching to the Magic1 cpu for all it's future Mac's. Apple's Fremont and Dublin plants are gearing up with state of the art wire wrapping machines to produce the new cpu. Steve Jobs will claim the ability of the cpu to scale to 3Ghz by next summer says Dovrack.
In the time it took Bill Buzbee to create his homebrew CPU, I perfected the artificial vagina. Coincidently, it too is constructed out of 200 74-series TTL chips wired with thousands of individually wrapped wires. Now I ask: whose time was better spent?

While the webserver is currently unresponsive, I am left to wonder why. If it can serve webpages at a rate of 3MHz, it is very fast. As we all know, 1 Hz is one per second, 1MHz is one thousand per second. The article stated that the home-built webserver was serving pages at 3MHz, or at a rate of three thousand pages per second. That is very impressive. Now, if the webserver was only processing instructions at a rate of three thousand per second, then it'd be totally screwed.

okay everyone, get ready to drag out your tired old jokes about the speed of the web server...
Creating your own CPU can be a fun learning experience but has this person never heard of a FPGA?
It is basically the same thing (you can create your own CPU) except much easier to work with since it would require much less parts.
I wonder how much power all those chips use?
No way I'll stick any part of my anatomy into that!
TTL uses power continuously, not just during switching states. So the load on the server should have no relation to the power usage.

If he can produce this with raw ttl gates, it can be produced with an fpga. Voila, a one chip web server which should run a lot faster than 3 MHz. (Of course, I haven't rtfa for obvious reasons.)
This is actually neat and useful.
... a lot slower than I remembered.

Now this is what geekness is all about. I remember back in the 80's while in school I designed a digital clock built entirely from TTL devices. Sure I could of just used a off the shelf clock chip, but that would be too easy.
"I bow to no man" - Riddick
Magic-1 is a homebuilt minicomputer. It doesn't use an off-the-shelf microprocessor, but rather has a custom CPU made out of 74 Series TTL chips. Altogether there are more than 200 chips in Magic-1 connected together with thousands of individually wrapped wires. And, it works. Not only the hardware, but there's also a full ANSI C compiler for Magic-1 (retargeted LCC), and a rudimentary homebrew operating system. You can even telnet into Magic-1 and play Original Adventure.
This web site has served as the development repository for the project, and contains lots of pictures documenting the construction, as well as full documentation and diaries stretching back to the project's beginning in 2001. You can also find a few videos of Magic-1 running, including the first time it worked.
Start here, and then check out the Overview and Photo Gallery. To dig deeper, browse through Technical Info, Construction - and if you're really interested, you can even download Magic-1's full schematics.
Magic
In the summer of 1980 I celebrated my freshly minted B.S. in Journalism by blowing most of the cash I collected in graduation gifts on a TRS-80 Model 1 computer. Sitting on the floor of my apartment I fired it up, typed in the sample BASIC program and then "RUN".
"BILL", I responded.
Wow! I was blown away. This was just a machine, but I could interact with it using language that we both understood. As a Liberal Arts graduate with next to no technical background, I found this completely astonishing. Over the next year, I continued to play with my TRS-80 Model 1 while working as a journalist on a small-town Kansas newspaper. I decided that I really wanted to learn more about how computers worked, so I went back to college and picked up a M.S. in Computer Science.
Now, more than 20 years later, I find myself with an urge to touch that magic again by building my own computer from scratch. By "scratch", I mean designing my own instruction set, wire-wrapping a CPU out of a pile of 74 series TTL devices and writing (or porting) my own assembler, compiler, linker, text editor and operating system.
I'm calling this computer the "Magic-1", or M-1 for short. It's a one-address, microprogrammed machine with one-byte opcodes. It features 8/16-bit data operations, functioning on an 8-bit wide data bus with 16-bit addresses (mapped via 2K-byte pages into a 22-bit physical address space). Code and data address spaces can be shared or disjoint, giving each process up to 128K bytes of addressing. User and supervisor modes exist, along with hardware address translation, memory-mapped IO, and support for DMA and externally-generated interrupts. As far as components go, it is built entirely out of 74LS and 74F-series TTL devices plus modern SRAM and old bi-polar PROMs for the microcode store. I designed it to run at 4 Mhz, but missed a couple of critical paths - so ended up at 3 Mhz. Goals
OK, so I understand wanting to do your own CPU, buy why on earth are you doing it this way? I mean, why TTL - why not FPGA? And really, 16-bit virtual addresses in a 22-bit physical address space! What's the deal with that?
I guess any project should start off with some notion what of what you're trying to achieve. My high-level project goals are: bullet
Touch the magic. By this I mean to gain a deeper understanding of how computers work, and specifically computers similar to those of the late 70's and early 80's that first fired my interest. For this reason, the Z80 loomed large in my mind throughout the design process, and running with an 8-bit data bus and 16-bit addresses just seemed right. Although I'm largely trying to use parts that would have been current in that time, I'm not shooting for historical accuracy. My choice of

Blinky lights~Real Computer
10 years ago I worked in a mainframe shop that had upgraded from the 4381 to a 9121. Neither system had much "eye candy". That meant that the client didn't have much to show off in the "big window" of the data center when tours/investors were guided thru.
Unless Tex was working.(and thankfully he almost always there). He was the client's rep that ordered paper by the semi for us & was able to bend Standard Register to his will with a mere phone call(one semi load of paper a year will usually do that, we did multiples)
Tex would lead the tour to the window and happily point to the elderly IBM network controller(box was actually blue on the sides, model forgotten) with all its blinking status leds and tell em "there is the computer".
They'd make "pretty lights" noises and continue along, Tex would grin from ear to ear & we'd have to wait till they left before we could run outta air laughing.
Tex dreaded the times anyone talked about network upgrades.
but waste of money
you could buy microcontroller and ethernet ready chipset for it for less than the cost of 200 ttls
and you'd get much better performance with that rig

Jeez, I have a headache already just thinking about this. "...thousands of wirewrap connections..". To learn microprocessors, I wirewrapped demo prototype boards in mid 1980's and eventually made one for each of the major CPU chips available at the time (Z80, 6803, 6809, 8051). Each one had 40 wirewraps on the CPU, 28 on the EPROM, 28 on the RAM, 30+ on the I/O, 24+ on the UART, 16-20 on each of the ADC and DAC chips, on and on.
Then getting the thing to work! Using crash-and-burn EPROM erasing and testing. Before being able to afford a U-V EPROM eraser, I'd have a 10-20 chips sitting on the garage roof. Slowly losing their minds in the sunshine.
Things are SO much better now. Highly integrated Atmel AVRs and PICs that program over and over directly from the parallel port of the PC and don't have to be removed from the circuit. Simulators that work. JTAG structures that allow the functionality of in-circuit-emulators that are built right into every processor chip. SPICE.Microcontrollers like the AVR Tiny13 that have 10-bit ADC built in, operate at 20 MIPS, reprogram 10000 times, run on 1 milliamp, a cost less than a dollar.
I still wirewrap when there's no other way to get a prototype built and there needs to be TTL logic or bus-interfaced I/O or sensors on the board.
But I get halfway through the building of the prototype and this horrid feeling just creeps over me. It's like being in a solidifying muck of concrete that is getting harder by the minute and you can't pull yourself out. "Why am I doing this?".
So someone makes a web-server out of TTL chips and 'thousands of wirewrap connections'. Show it to someone like your boss and they'll say, "Cool, now make ten more". Then realize that by using modern tools, you can do the same thing in a FPGA that costs a few dollars. And make modifications that take a half-hour to write. And don't require connecting 50 logic-analyser little connectors, or studying miles of logic charts until you go mad, or trying to find the one broken wire in the six-deep layer of wires on the back of the wirewrapped board. Or finding that the one broken wire is the bottom wrap on a pin that has three other wraps on top of it...
It's called progress, gentlemen. Take advantage of it.
Come on guys, this is 3,000,000hz! That's like, wow.
Modern computers come with like 2.4 or something. This is wAY WAY faster, no way will we slashdot it.
back in the 70's I had to build controllers for video switching equipment with TTL gates, but I'm just wondering what this 4 year+ project proves in 21 century. Heck, I haven't even wirewrapped a board in 15 years; there's better ways of doing EVERYTHING now.
I mean, just imagine!
Not sure if it fast enough but..

Hey Steve, I know that IBM's Power PC chip has turned out to be a big disappointment. You're looking to cash in on CPU savings similar to what Dell is experiencing with Intel that IBM hasn't been able to provide. The G5 is as close to going into powerbooks as it was a few years ago. My suggestion to you is to consider using the Magic-1 CPU. Assembly is a snap! Sure, if you were to have it assembled in the US it would cost a pretty penny, but why not give our friends in Bangalore a chance? Sure, I understand that speed is a concern and that this CPU is only 3MHz. Well, dual core CPU's are starting to come out and quad core CPU's are on the horizon. You've always been an innovator. Why not have a 1000 core CPU? Can you imagine the press you'd get? All the hipsters would have to pause their iPods for a breif second in recognition. Hold the phone, you want more? How about this. This new system can be setup to launch different applications randomly. Starting up the applications you want is so passe. People love surprises. LIFE IS RANDOM.

When our interns or junior staff start complaining about mundane work, I show them pictures of wire-wrapping and tell them that used to be what the interns and junior staff did when I was learning the ropes. That ususally shuts them up for a while...

Is this an Amish version of a web server or something? I know the Amish insist on doing things the hard way, such as plowing a field with a horse. Why would a person choose to build a system today using old tech such as this? Must be some religious thing or perhaps a new Amish Sect? Compish? Or is it simply Stupish? ;)
Sure, a 3 MHz TTL device isn't going to compete with anything comtemporary, particularly a commercial microprocessor.
True, nobody is going to buy one due to the labor cost to build it.
But can anyone think that it was built to set the world on fire? Has nobody but me ever built something simply for the love of doing it, or the knowledge gained from figuring out how to do so? There's more to building something (whether it be from a kit or personal design) than the usefulness of the end result.

So, if a guy wanted to build a more "modern" homebrew CPU, what options are there? Are there any decent CAD tools that don't cost a thousand million dollars? And once a layout is done, is there anywhere you can get just one single chip made for a reasonable price?

2. Wow! This guy really needs to get a life. You know, meet a few chicks, go bowling... something.
Some mornings it's hardly worth chewing through the restraints to get out of bed.
Actually as part of our senior project, we had to build a CPU using TTL gates. And that was for the EE. The ME was an complete manufacturing line.
200 TTL chips for the CPU, $60
Wirewrap boards to put the chips on, $20
Wirewrap wire to hook everything up, $20
turning on your webserver, only to be slashdotted - priceless!

Did the editor really need to keep in the link to the actual web server? Like a 3Mhz server made out of hundreds of small chips is really going to withstand a link on slashdot! Why even include it?
The regular site is down too, so screw all your "RTFA" guys, we can't unless we use a google cache or mirrordot.

Even though that joke was fairly predictable, it isn't fair that the poster should suffer a net karma loss for it despite the +5 funny total score. Shame on whoever gave that post an overrated moderation, may remorse be yours forever.

The most incredible wirewrap project I ever saw was CMU's original Warp computer, a 10 CPU array computer, all wirewrapped and running at 10 MHz. Each cell had 255 chips and drew 136 watts peak. The whole array delivered 100 MFLOPS peak and about 30 MFLOPS on real problems. Apparently the price/performance was quite good by the standards of the day (1986).

The boards themselves were an incredibly dense thicket of wire wrap. You could barely see the board for the layers and layers of wiring. I looked for a photo on the web but couldn't find one. Here's a paper describing the project:

Eventually this is how you will get a DRM free computer, if you dont know how to deal with FPGA's that is...
---- Booth was a patriot ----
now if it had handeled slashdot at only 3mhz.. we wouldhave needed to test it with botnet.. but it is dead so Nothing to see here ... please move along

Well you see, M1 to M4 were not entirely successful. This one is. M5 is ready to take control of your ship.
When I was attending tech school in Western NY in the late 70s there was a nearby computer store run out of a guys basement. He also had an '8080' that he built out of TTL in a rack mount that ran at 10 Mhz. Probably the fastest implementation of the architecture at that time !
Come now, you should know that /. editors don't give a rat's ass about little things like bandwidth. They've got network pipes thicker than Paul Bunyon's sausage, racks of servers, and a readership in the thousands; I think they get a kick out of DoSing the little sites. Sort of like frying ants with a magnifying glass.
In all seriousness, people have suggested that they at least mirror small sites at the initial posting and they have steadfastly refused. Hell, a link to a google cache would be better than nothing.
Humorless sig goes here.
i'm not gonna post how this ttl cpu has melted into little bits of plastic and metal. Instead, I'm imagining a Beowulf cluster of these cpus. And that's making me laugh even harder.

Very cool project. Might have killed for a front panel like that back when I was working on Z80 projects -- especially before logic analyzers became affordable.
For a homebrew project, that's a serious amount of wirewrap. At least he used RAM/EPROM/UART chips, instead of a _lot_ more flip-flops and other gates.
Two things struck me as strange though. Why was the front panel done LSB to MSB instead of the more common (certainly more readable) MSB to LSB? Also, why wrap virtually everything in the same blue wire? I always tried to do power/ground/signal (at least) in different colors -- may have made his missing memory ground wire easier to find.
You guys are such dicks.
did anyone get a glimpse of how much the rig cost? i am the first to admit the cool factor, but geeze, that must have been alot of time and money if every in it wasfrom scratch.

And no, I'm not a M$ supporter. Just the first two topics that came into my fatigued brain at this hour.
Id love to try somthing like this, but be really great if there was an HDL to ttl 7400 series synthesis tool. Anyone know of software that would take either verilog or VHDL and rather than mapping it to an FPGA or somethings, generates circuit made out of 7400 series chips?
Why not use an FPGA instead? You could have the same design flexibility with a lot less wire wrapping.

Well, maybe not the webserver part...
When I was an EE undergrad at Ohio in the 1970's, I had heard that a fellow in the accelerator lab across the way had built a TTL-based computer which ran at 20MHz (I *think*). I tried Googling it, but I didn't find any references. So, I never actually *saw* it and it's a nearly thirty year ago memory. Take it with whatever sized salt you'd like.

You finally made it to the front page of /.
About time too.
I've been following this guy's progress for more than a year now - sometime before he had the final schematics finished, and well before he actually started building anything.
This is the uber-geekiest project ever and I'm quite dismayed by the number of posts that are saying, effectively "So what? He could've bought a better computer off the shelf!".
Bah! To all you naysayers. This man deserves a Hacker-of-the-year award for seeing this through.

Out of gross curiosity is /.ing a DOS?????
Seriously, that's pretty much what they were, just piles of TTL logic chips and strung-on-wire graphite beads for memory, all on pizza-box-size boards that slipped into a big chassis. You needed at least three boards, one for the CPU, one for memory, and one for I/O. The first minicomputer I worked with was a Data General Nova 1200. 1200 as in 1200 nanoseconds PER INSTRUCTION. That's a whopping 833 KHz. And a stunning 8 kilobytes of memory. It was amazing what we got that thing to do, though.
You can tell you're getting old when people start reproducing the obsolete crap you're happy as hell to have left behind.

check for a cache before you post that!
Having said that, ok it was MEAN!
Hemos, you're a tactless fucker. You read the blurb, you know it's only a 3MHz machine, you KNOW that millions of slashgeeks worldwide will click that link and bring that guy's machine to a halt. Don't say it's stress testing, don't say anything like that.
Have a little common sense (and maybe some respect) and don't link stuff like this on the front page. Link a mirror. Hemos, you're pretty nerdy I bet, I'm sure you can use wget to mirror somebody's site and find a place to host it for a while. I mean, if it's a tiny page on a 3mhz computer, it shouldn't take much to mirror it and be nice to the fellow and his project. Or even a coral cache link would be fine, so we don't break this guy's handmade computer.
Have you ever hand-made something as an imitation of something else which is bigger/better/more powerful than your imitation, and then had somebody come along and use your imitation just like it's the real thing, and break it? Any adult who constructs model aircraft and has children should know this one by heart. Hemos is the annoying child who comes into our garage and plays with our model aircraft like they're toys and eventually breaks them because he doesn't understand that they aren't toys. He's actually a lot worse than that, because he's inviting over a million of his friends to come into our garage and play with our model aircraft like they're toys, ensuring only that they'll get broken faster and those with the mental capacity to enjoy the models as something other than toys will be left with nothing.
I mean, really. I am not trying to be a troll here at all. Does anybody else see what Hemos did as totally tactless?
Reinvent the wheel only at either a lower cost, greater effectiveness, or your own personal enrichment and satisfaction.
I'm used to seeing such kit accessorized with twenty years of dust bunnies and dead roaches.

Oh come on! If I put together something like this I would WANT it to get slashdotted! Years from now you could pull it down from a shelf.. or point at it in the corner and say .. I made a CPU and it got slashdotted!
The ISP may not be too happy though : )
for shame
your thin skin doesn't make me a troll
If he has a dynamic IP, it's simply a matter of making a new request. He just has to make sure that his dynamic DNS service doesn't update until the /. effect dies down. :)
Amazing things can be done with a few measly logic gates and a few machine code instructions. Heck, you think a webserver made of 200 TTL chips is crazy? Check this out. About halfway down the page is a description of the R-741 computer, a minicomputer built in the early '70's to run robotic machinery. I doubt it even contains half as many as 200 TTL chips, and running at 4 MHz on a custom instruction set, this thing's operating system, coming in at a whopping 21k, runs all the functions of digital and analog I/O for robotic machinery--under a complete language interpreter! And it's faster at some functions than many modern computers, given that its electronics, instruction set, and software were all designed so tightly that not a single chip or wire was used unnecessarily, and not a single clock cycle was wasted. Today's general purpose machines, with their zillions of logic gates and gigabytes of memory, are weighed down by layers upon layers of stuff.
It is truly refreshing (and a priviledge, I suppose) to work with this R-741 machine. And it's quite refreshing to see someone build a webserver in a similar style. We need more of this type of ingenuity, and less mountains of bloated code that work too hard to do things that are basically very simple.

God.. that was the best laugh I've had in weeks.
Yes, the server is going to go down heavily. But this is slashdot, not... hmm... I can't think of any other news site forum like slashdot but with less of a punch..
Ah, you found me!

Does it go on forever?
BTW, the Cinematronics arcade hardware used a similar approach of building a CPU out of TTL logic. In that case it was able to run at 5MHZ, which was faster than microprocessors at the time (the Apple II, for instance, only used a 1MHZ 6502).
It's amazing to me how few components it takes to create a fully functional CPU.
