            CS and other hobbyists get all sniffly for the good old days. I was having a huge amount of fun a couple weeks ago hacking a 6502. That we even recall such an occasion should suggest to you that so long as some of us are alive, remembering and playing around with such artifacts defines who we are.

            1... Why not? People are synthesizing other CPUs that aren't really 'useful' in these days.

            2... Because you can!

            3... Because its part of our history, and keeping these things alive is part of our duty to preserve the history of computer science, even if a synthesized core is only the chip in question from an external point of view, it still preserves the memory.a well written VHDL specification should document how the chip works for anyone in the future to examine.

          • One might as well ask why anyone would bother building a working Babbage Difference Engine, yet it has been done (and the sucker works too!). I suppose the rationale for building a trebucet is slightly more obvious (throwing things a long distance).

My father even tried to get me interested in hobby computing, as opposed to my high-voltage experiments with transistors, capacitors, resistors and other things which could explode and poke an eye out. Eventually I got access to a DEC PDP system while in Explorers (at Dow Chemical in Midland, MI, no less) and once I discovered big, huge, high current processors (all TTL logic *8^) you could fry an egg on, I've never looked back. (much like today's P4 and Athlon, hey Thanksgiving baking tip, toss a turkey in one of these machines and cook it in half the time!)

      Maybe some day, when I get tired of making small electronic curcuits explode, I'll get one of these and build an SAP (simple as posssible) computer out of one, just for jollies, assuming I still have eyes left.

        This is true. The 6502 was a competitor to Intel's 8080. The latter was much more powerful (and the later Z80 by Zilog was like an 8080 on steroids), but the former was cheaper... IIRC something like $400 for the 8080 and $250 for the 6502 (and these are mid-70s dollars). Also the support circuitry for the 6502 was simpler, further reducing cost.

        Pardon if I got some facts wrong, age and alcohol have taken a good number of brain cells :)
        • The 6502's initial excitement was the price -- it was the first real $20 microprocessor. The 8080 cost quite a bit more in 1976. The 6502 was, I would suggest, a far more elegant chip than the 8080. The 6502 was Federico Faggin's second microprocessor. He did the Motorola 6800, then jumped ship to MOS Technology. The 6800 was loosely inspired by the PDP-11, a very nice machine for the day. The 6502 rethought a few of the 6800's design decisions and was even nicer. Apple picked the right chip.

          BTW the original 6501 was pin compatible with the 6800, but didn't ship because Moto made some threats. The 6502, I think, added an internal clock; there were a bunch of other 65xx chips that followed. Rockwell was the second source and kept the line going after MOS Tech, which had been bought by Commodore, tanked. I think it's still fairly popular in the embedded world.

          The 8080's instruction set was more reminiscent of the PDP-8, and rather ugly. The 4004 was not really a microprocessor, just a controller, because it lacked interrupts and some other features needed to be a "computer". The 8008 was a major improvement. And only 18 pins -- a lot of jelly beans needed to run it! The 8085 was the easier one to glue to. I recently read an article explaining the history of those early Intels, but I don't recall where.
      • Actually, MOS Technology, and how the lawyers allowed those two companies to co-exist in the same market I'll never know.

        I liked the 6502 instructions. There was an elegance to them, a symmetry that seemed missing in the 8080 and its ilk. When in doubt, Intel threw registers and special instructions at the problem (never mind the Z80's two complete register banks), whereas MOS seemed to favour soft solutions (don't need no stinking "multiply"), and of course memory-mapped I/O.

    The 4004 was certainly a significant milestone, but I think the 8080 launched in 1974 was truly the "Model T" of the computer industry. That was the chip that was general enough to really run everything. It was the basis for all the microcomputers and the CP/M operating system.

    In fact, I believe Zilog Z80s (an 8080 clone with some extra instructions -- around 1977?) are still being manufactured as controllers in various products.

      In fact, here's Zilog's page on the Z80 [zilog.com] still in production after 25 years! How many other computer technologies do you know that are still available after 25 years? Pretty remarkable.

      Talk about a company milking something for all its worth! :)

      • If you write assembly programs for the TI-83 graphing calculator, you're writing in Z80 assembly. I don't know if they actually use a Z80 chip, or if they're using a clone or a faster-but-similar chip.
      • I agree, the Z80 is an important bit of technology. Is there any CPU that has gained such wide acceptance or been in continuous production for so long?

        Still, the Z80 now is nothing to what it might have been. I remember when Z80/CPM systems were the standard for serious desktop computing. Even Apple II people used a Z80 card to run business apps. (There was a MS version -- their first hardware product!) I think this Apple/Zilog combo was the most common desktop business computer at one time. If things had gone just a little differently...

        • It's worth pointing out that Zilog came out with a Z8000, which was a 16 bit version of the Z80, but it was a massive failure. The other competitor, of course, was the 68000 (which Apple chose). The rest of the industry (read: IBM) picked the 8086. I don't think the Z8000 was ever really in the running. I don't know much about it, so I'm not sure why.

          Trivia: I actually saw an early prototype of an IBM PC that used a 68000 microprocessor. Really! We were contracted to port some products to it (our shop had a bunch of 68000 products), but the contract never came through for obvious reasons.

          • Having had the pleasure of programming the Z8K, it was not a 16 bit version of the Z80.

            The Z8000 was available in four flavors:

            Z8001 Segmented (8MB address space)

            Z8002 Non-Segmented (64KB address space)

            Z8003 Segmented (8MB address space), Virtual Memory Support

            Z8004 Non-Segmented (8MB address space) Virtual Memory Support

            The Segmented CPUs had a flag bit that allowed them to run in non-segmented mode.

            The Z8000 was much closer architecturally to the 68K family than the Z80/x86 family. It had 16 orthagonal, 16-bit registers (R0-R15), which could be paired up as 8 32-bit registers (RR0-RR14). R15 (non-segmented mode) or RR14 (segmented mode) was the stack pointer.

            The opcode names were similar to the Z80, but the architecture was vastly different. The Z8000 series was popular in embedded and military applications. Unfortunately, I don't believe Zilog ever built the Z8070 FPU for the processor, which also hindered it's acceptance as a mainstream CPU.

            Anyone out there remember the Zilog ZEUS System 8000? It was a Unix System III variant.

            • Anyone out there remember the Zilog ZEUS System 8000? It was a Unix System III variant.
              Was working for Zilog at the time. ZEUS (Zilog Extended Unix System) came out before System III was officially released. Pretty sure it was based on V7, not System III.

              At the time I thought this was Big Stuff. Unix on a microcomputer! But in hindsight, you really need a VM to have a serious modern OS. That's why there's no Linux for the 80286! I think the first commercial Unix to do this was CTIX, which Convergent Technologies created (System III/V, with the BSD VM, running on a 68010 with proprietary memory management hardware) for its MegaFrame box. The MegaFrame was a disaster (tried to be too many things at once), but it paved the way for the first 680x0 Unix boxes -- Convergent's main claim to fame before they were absorbed by Unisys.

              • ZEUS (Zilog Extended Unix System) came out before System III was officially released. Pretty sure it was based on V7, not System III.

                I'm pretty sure that uname indicated SysIII. Of course, that was ZEUS 3.1 and 3.2. YMMV for earlier versions.

                Was there really any difference between V7 and SysIII?
                • That's a very good question. On the one hand, they were quite far apart on the Unix family tree [wanadoo.fr]. On the other hand, I don't recall anybody abandoning their V7 ports and starting over with System III, when AT&T decided that the latter was the official commercial Unix. Probably everybody just folded in System III features. I'm guessing that V7 backward compatibility was never an issue, though I'm hardly the expert.
          • Actually, I was working for Zilog at the time. I wasn't working on the component side (I was hired to document their Z8000-based Unix box), but I seem to recall that the Z8000 was a substantial change in architecture from the Z80. There was a school of thought that said that 16-bit processors should not try to be backward compatible with 8-bit processors. Thus Motorola chose to design the 68000 from scratch, rather than upgrading the 6800. I'm pretty sure Zilog made a similar decision.

            By contrast, Intel saw the 8086 as a continuation of the 8080. So they came up with this segmented architecture that looked much the same as an 8080 at the 64K address space level. (The binaries were different, but you can port an 8080 assembly program simply by resassembling it. Which is why Microsoft Basic was so slow on DOS!) Bad from an engineering point of view (we still have issues with memory models on Windows!) but that sort of cautious technology probably had a lot to do with Intel beating out Motorola to provide the PC's CPU.

At an entry level cost of around US$ 18,000 it was easily affordable by most businesses and universities who needed a computer. There were enough of them made that a lot of third parties developed add-ons. Also, there are still a few PDP-8's running production applications as controllers for manufacturing machinery.

      • The Zilog had a much larger instruction set and many of the shared instructions executed in fewer CPU cycles.

        Well, "much larger" is a bit of an exaggeration, although there's no doubt they added a bunch of useful instructions. What really rocked were the extra registers. They really came in handy.

        The 8-bit processor that really gets no respect is the Motorola 6809. Lots of registers, and the instructions set was orthogonal with respect to them. It was great, but not really widely used for some odd reason.

    • I can think of several candidates for the first single-chip microcontroller. The very first one in commercial production was probably the Texas Instruments TMS1000, although I think they may have had an even earlier version (TMS0970, perhaps?). These were four-bit microcontrollers.

      The first 8-bit single-chip microcontroller may have been the Intel 8048, introduced in 1976. It had masked ROM; there was also an EPROM version, the 8748, and a ROMless version (for external program memory), the 8035.

      Another possibility for the first 8-bit microcontroller may be the Mostek MK3870, which was a single-chip version of the Fairchild F8 processor family.

    I've missed out the Xeons, and of course all the
    microprocessors that didn't have some lineage
    to the orignal 4004. Although the instruction
    sets changed a lot particular from the 4004 to
    8080 and from the 8080 to 8086, there is enough
    similarity in there style and content to claim
    that your Pentium 4 or Athlon XP is directly
    descended from the 4004. It makes you wonder
    if Intel can really expect to shift people from
    the x86 arch to a totally new one.

    Still utterly unused, in anti-static foam, three Intel 4004s. My roommate decided to start collecting old CPUs, and I managed to find these, free. I still want to make a very simple blinking-lights toy with one of these, and proudly put the "Intel Inside" sticker on the box :)

    Goddess, this brings back memories! Hanging out at the library, using their terminal to call (at 300 baud, that was *fast!*) the HP-2000 system at Harper College, and chatting with friends who had serious money (Jeff actually *built* an Imsai 8080 unit, though he got many of the parts free by schmoozing the sales person).

    30 years, gads. Back then, having even a floppy disk was a wild dream, now we have 100+ gigabyte hard disks. Back then, having one whole K of ram was heaven - last week, I bought 512 meg for $20. Back then, the clock oscillator could be made from a simple L-C circuit, and it ran several hundred kilohertz. Now, it's a PLL-controlled internal oscillator, using an external crystal oscillator, all running at frequencies that make a microwave oven look slow.

    All this, in thirty years. That *really* makes me feel old :)
    • Yep.. The data sheet crows about how the 4004 can handle what would now be called 4K of ROM and 640 bytes of RAM (though it was measured in bits back then).
      and it could add two 8 digit integers in just under a second (probably stored in 32 bits as Binary Coded Decimal)

      And I moan about how my secondary computer has 'only' 96meg of RAM in it....

    • And just think... Harper College still uses an HP-UX system that's not much more powerful than a 4004 :-P

    I did some programming for the 4004 back around 1975, I had no idea it was that old of a chip. Of course I was working for the military, so that might explain it :)

    As I recall we had a Model-33 Teletype for software development. We punched the program into paper tape, called up a system using an acoustic modem and used their cross-assembler. Or maybe I'm just having an antacid flashback.

      No, I was doing the same thing during the same period. Disk storage was expensive and video display even more so. The KSR-33 Teletype provided cheap substitutes (paper tape and continuos-feed printer) for both. The damn thing was everywhere, and its design influenced the keyboards we still use. Oh yeah, and that's why Unix/Linux serial interfaces are still prefixed with /dev/tty.

      I worked for a company once that tried to do away with the ESC key -- a key which doesn't make sense except on a teletype. Everybody made fun of us for it.

      The KSR-33 was such an important part of computer culture that William Gibson put them in his classic cyperpunk novel, Neuromancer. Ironically, the Teletype Corp discontinued production of this model in 1984, the same year Neuromancer was published.

  • Wouldn't it be more appropriate to make a bigger deal when this thing is four thousand four years old? Or perhaps, when it turns 44?

    I've been waiting for the year 2015 to be the first poster with the story. I was really looking forward to all the extra karma gained with the mod ups.
    Dang, foiled again.

    I'm 33 and that ain't middle-aged. I take offence! :P
    • Not to worry my son,

      According to my calculations, it's not 30. It's 29.99999... Did I mention I'm running a Pentium 75?

    • Wow, 33? I think we've just found the oldest person on Slashdot. I mean, 33 years ago. . . that's like, the sixties, right? How did kids ever grow up without the Internet?

      If we take Moore's law and extrapolate. . . 33 years is 396 months, so technology must be 2^(396/18) = 4,194,304 times more advanced now than it was then. Did you guys even have fire yet, or were you still confined to nice warm Africa?

    Intel summed up the "speed" [sic] difference between a 4004 and a Pentium 4 with an interesting assume-this-basketball-represents-the-sun-like analogy: "Intel's first microprocessor, the 4004, ran at 108 kilohertz (108,000 hertz), compared to the Pentium® 4 processor's initial speed of 1.5 gigahertz (1.5 billion hertz). If automobile speed had increased similarly over the same period, you could now drive from San Francisco to New York in about 13 seconds."

    Hey, seriously, wouldn't it be groovalicious to have a bunch of 4004's produced using today's .13 micron technology, making them a tiny fraction of their original size ? Throw down a hundred of them on a board and have it run a massively parallelized app of some sort at 25 cents per node.

    Why the hell not ?
    • That's an interesting thought, and it's not the most ridiculous idea I've ever heard...

      The reason it makes sense is the same reason USB is in the process of displacing IEEE 1284 (and the reason RDRAM probably seemed like a good idea at the time) -- in theory parallel is faster, but the simple fact is that it's substantially more of a pain in the ass than serial to get working. The basic idea is to put several gazillion 4004 cores on one chip (perhaps something of a PGA-like device) and just bite off as much processor bandwidth as you need. I think the operative concept here is "dynamic pipelining" -- does that make sense to the sandbenders around here?

  • You might want to read the interview with Ted Hoff
    This interview credits Hoff with inventing the microprocessor. I think crediting any single person with "inventing" this device is a silly oversimplification.

    But Hoff did accomplish something important -- a lot more important than inventing a particular gadget. He demonstrated that simple general purpose computers could be built that could replace a lot of the complex custom hardware that was then being built. In so doing, Hoff started us down the road to making computers ubiquitous.

    I hacked the 4004 when I was a student, back around 1977. My work-study mentor had a contract with Monsanto, working on the machines that made the very first production plastic Coke bottles. These bottles were heavy duty, like little dark green wiffle-ball bats. The bottles were taken off the market pretty quickly, because of some problem with the plastic they were made from. I still have one.

    Anyway, a conveyor belt dropped bottles from a wheel going around (a horizontal disc) onto straight rows of pins, also moving. Required some trigonometry and timing, especially when starting the machines up. It was controlled by a 4004, the code lived in 7 256-byte uv eprom dip chips.

    We had an assembler written in Fortran, it ran on either a Honeywell 1648 or a Dec PDP-10 (both notable machines in ARPANET/Internet history). When I got there, they used to type the hex assembler output into the prom burner by hand! Burning the 7 proms took 18 hours of person time, and was error-prone. I wrote some code to do the eprom download automatically, with a paper tape or something, cut the process down to an hour and a half, made some folks pretty happy.
