486 Turns 15 Years Old 495

wooby writes "The 486 processor , introduced in 1989 at 25 and 33MHz clock speeds, is now 15 years old. Intel's simultaneous launch of both the 486, a CISC chip, and the i860, a RISC chip, was a gamble. Remarks Intel's former CEO, Andy Grove: 'our equivocation caused our customers to wonder what Intel really stood for, the 486 or i860?'"

        It doesn't look like you ever actually used one much. Funnily enough (given the parent article), I had the pleasure of using the Happauge 4860 motherboard [megasat.ch] which took both a 486 and 860. It was great - I could run UNIX on the 486, and then compile and build 860 programs, running programs on both processors simultaneously. It was good for me, because I could use the 860 simply as a coprocessor, but a very powerful one (it left even a 4167, let alone the 486's onchip FPU in its dust..), never having to worry about actually dealing with an i860 OS (of which there were some ,but I never had one...)

        For all its quirks, I wouldn't agree that the 80860 was a sucky processor. It was fast, but weird. Faster than anything else out there, mind. There were no Alphas back then. It left the 486 in its dust, at least until the very latest 486s (100MHz DX4s, etc)

        It was also the first non-RAM million-transistor chip from anyone, ever. :) And on that note, in typical Slashdot style, the article has a simple factual error: the 486 and 860 were _not_ released simultaneously; the 860 came first.

        It is wasteful, for two reasons: 1) the newer processors consume more power plus the multitude of fans needed to cool the thing. 2) there are millions of 386 and 486 machines still functioning out there. its wasteful to build a new 2GHz machine when a 486 can do the same task.

        Plus those 'old' computers are a lot more durable than ones made today. The old XT keyboards were made from steel. Even into the late 1980s, IBM keyboards still had a steel plate underneath. The IBM PS/2s had steel cases, you could use the case in place of cinder blocks to raise up your car.

        My parents had a Hayes1200 modem that they discarded. It had a milled aluminum case. Being a 10 year old at the time, I decided to break the thing. I took a sledge hammer to it, threw it around the back yard by the cord. It still maintained its shape, I couldn't dent it. Try that today with any new equipment.

        These are same reasons they still have the original elevator motors in the Empire State Building. "They simply dont make motors as durable as these anymore. They've been running continuously since 1933."

          If you long this, Matias has build a mechanical keyboard called the Tactile Pro (google it buster). It's simply an awesome keyboard like they used to be. It's based on the same mechanical keys that Apple used to have on it's Apple Extended Keyboard (aka, Mac SE and Mac II era). They had to secure one million key switches from the manufacturer in order to keep them in production.

Despite of all pretty eye candy, software isn't what it used to be. "My computer is too slow" is an excuse often heard instead of "my software is badly designed".

That was great until someone hit his room with a leaner and hosed his whole backup system (which was on the floor). For all you who don't know what a leaner is, it's when someone fills a garbage can with water and tilts it against someone's door. When they open it, the water splooshes over everything, especially them. Pretty nasty! We used mirrors to check for leaners so they never got us. :-)

        When trapped in your room by a live leaner, crack the door open a little bit, then snap it closed. If you do it right, the leaner will be diffused.

        Then make sure you find who did it and penny them into their rooms. That's a lot harder to open from the inside ;)

    BLURB

    Intel's venerable 486 CPU is now 15-years-old. Intel began working on the 486 in the early 1980s, and introduced the chip in April of 1989. The 486 was essentially an improved, modified version of the 386. The 32-bit 486 was initially manufactured on a one micron process, and was introduced at speeds of 25 and 33MHz.

    All 486 chips except for the "sx" versions came with a built-in floating-point unit and contained 8 KB of cache memory. The 486 was capable of 20 MIPS performance, and contained certain features (such as pipelining) which had previously been found in mainframes. As a result of these enhancements the 486 was theoretically able to execute one instruction per clock cycle. Today's processors have clockspeeds 100 times faster than the original 486, but the instructions per clock (IPC) of the latest CPUs isn't much better than the IPC of the 486. Intel also decided to release the 32-bit, superscalar i860 CPU, which was specifically designed for scientific applications, in 1989. In Only the Paranoid survive, Intel's former CEO Andy Grove recounts the dilemma of launching two largely incompatible CPUs at the same time:

    We now had two very powerful chips that we were introducing at just about the same time: the 486, largely based on CISC technology and compatible with all the PC software, and the i860, based on RISC technology, which was very fast but compatible with nothing. We didn't know what to do. So we introduced both, figuring we'd let the marketplace decide. However, things were not that simple. Supporting a microprocessor architecture with all the necessary computer-related products - software, sales, and technical support - takes enormous resources. Even a company like Intel had to strain to do an adequate job with just one architecture. And now we had two different and competing efforts, each demanding more and more internal resources. Development projects have a tendency to want to grow like the proverbial mustard seed. The fight for resources and for marketing attention (for example, when meeting with the customer, which processor should we highlight) led to internal debates that were fierce enough to tear apart our microprocessor organization. Meanwhile, our equivocation caused our customers to wonder what Intel really stood for, the 486 or i860?

    Compaq recommended to Intel that it abandon the i860 and concentrate all of its efforts on the 486. Microsoft pressured Intel to promote the i860, and strongly encouraged Intel to introduce an i860-based PC. Intel decided to emphasize the 486, and ended up selling hundreds of millions of 486 processors. It is intriguing to think of how different the computer industry would be today if Intel had decided to emphasize the i860 instead of the 486.

    486 engineering samples were available in June 1989, but they were buggy as hell. There were several severe problems with features such as the page table logic in early steppings.

    Later in the year, IBM introduced an upgrade kludge 486 piggy-back board that could be shoehorned into their 386-based PS/2 Model 80s. However, IIRC, these all had to be recalled due to the bugs in the early 486s.

    End users didn't get to see a significant number of correctly functioning 486 systems until early in 1990.

    BTW, if you ever saw the processor specs for the i860, its byzantine complexity made the x86 architecture look clean and elegant. There's no wonder it never took off.

    Though my friend managed to cook one by plugging it in backwards, he said the chip glowed red. And after it was cooled back down a small chunk just fell off.

    Well, given the problems that people had getting general workloads to run on the i860, probably almost nowhere...

    But this always raises the question of what the world might have looked like if intel had dropped the ball and forced the PC world to abandon the x86 world in favor of another architecture. Given the time frame, the other architecture would almost certainly have been RISC. Who would have won, and why? And how would the world look now if we had the descendents of the MC86000, Sparc, or MIPS R3000?

    I'd wait for the day the Pentium turns 15. I remembered the days of the popular Pentium bugs that affected various 60-100Mhz versions.

    And who'd forget the classic that went something like...

    The Pentium was not officially named 586 because 486+100 turned out to be 585.9999999999999.

    I think the Intel 80486 CPU will be considered a great CPU, though it pales in comparison to the more significant importance of the 80386, Pentium, Pentium II, and Pentium 4 CPU's.

    The 80386 is definitely important because 1) it introduced the 32-bit flat memory model, something that subsequent Intel CPU's incorporated, and 2) it could virtualize 8086 sessions, which made it possible to run multiple programs safely (remember what a breakthrough QEMM-386 plus DESQview was?).

    The improvements that the 80486 brought was essentially a built-in FPU unit and faster clock speeds.
    • It was the first x86 chip with an instruction cache. This is significant not only because of the speed increase, but because the 486 was the first chip that unmodified 8086 software started having compatibility issues with. Frequently, the only solution was to disable the 8k internal cache, and I remember downloading several programs from a local BBS which managed to do just that in various ways.

      The instruction cache is what makes a 40Mhz 386 (with a 8Mhz turbo toggle) the king of oldskool gaming. It jus

    I would feel that the release of the 386 was much more significant of a technology release then the 468.

    I mean really, the 486 was just an overblown 386 anyway, it wasn't a true 'advancement' like it was from the 286...

    Or i suppose anytime we jump to a wider word....
    • The 486 was a huge advancement over the 386. Take a look at the instruction cycle counts of the two chips, plus it had the first integrated FPU in the x86 series. Unfortunately, because of the 486SX (SX = sucks), programmers were unable to rely on the presence of hardware floating-point.

    Our 486 had 16MB of ram, which I thought was bordering on absurd at the time. I didn't know anyone else with more than 4MB. But when time came to do a video for a class project, I did all the sound editing on that thing. For the 7-minute video, we had about 9MB of audio, and so I was able to edit it effortlessly with the Sound Blaster software.

    Oy!

    Don't take that 'pcmech' website the article links to very seriously. It's an interesting read, but contains so much stuff that is downright *wrong* as to be good for a laugh.

    "Despite this, the 186 never found itself in a personal computer."

    Bullshit. I owned one. Made by PCTech. Yes, the same one that made the buggy IDE chipset we all know from our kernel configuration sessions. Ironic in that the 186 motherboard they made had onboard SCSI. Quite the piece of work for ~1987.

    "The 286 was the first 'real' processor."

    Ummmmmmmm...Whatever you say.

    "it could not switch back to real mode without a warm reboot."

    Bullshit. I guess exiting Windows 3x on a 286 and going back to that DOS prompt was a figment of my imagination.

    That's only halfway down the first page. It only gets worse.

      That one is actually true.

      Officially, once turned on, you could not leave the protected mode on the 286. IIRC there is an undocumented 'loadall' instruction which allows you to do this though. But I doubt Windows was using that one. Instead the BIOS provides functionally to exit protected mode by doing a silent warm reboot (It puts some magic value into the CMOS RAM, causes the processor to reboot and the bootup code checks for the magic value and returns to the OS).

        He's right. Mod this up.

        Intel designed the 286 to run UNIX, or a UNIX-like OS. PDP-11 era UNIX, with an address space with 64K protected segments. Each process was to be limited to a few 64K segments. Back then, everybody thought that the hardware had outgrown DOS, and it was time for a real OS.

        AT&T built and shipped the "AT&T PC", which actually worked that way. It didn't sell, but it did work. It was just like running UNIX on a PDP-11.

        Intel never intended the machine to be used as a psuedo-flat address space with base/displacement addresses. Let alone use the hacks that led to "extended" and "expanded" memory.

        With the 386, Intel got the architecture right, and that's essentially what we have today. But the 286, even though it was the mainstream machine during the years PCs really took off, was fundamentally broken.

    The constant race between AMD & Intel and Nvidia & ATI to make their products faster has undoubtedly been good for their bottom-line, but is it promoting laziness in programmers?

    In the pre-PC days (and to a certain extent games consoles today), the hardware platform remained static for the life of the product. Compare the software released at the beginning of it's life compared to the end - it's streets ahead, particularly games. Coders had no choice but to continually optimise their code, learn new tricks etc. With the advance in PC hardware there isn't the same motivation. You know that when you start a project that by the time it's released the 'average' platform will be more powerful. Won't run on smoothly on a 2.6GHZ P4 with 32MB graphics card? No problem, we'll put that as the minimum spec and recommend something higher.

    It's a 486DX4/75 laptop w\ full docking station. (back in the days when a docking station was huge and literally converted the laptop into a desktop) I have it up and running as a fully functional backup desktop computer. It's got Windows 95 and can surf the web (Netscape 4) and even play music through Winamp. And it's on the network. So if I've got my main box offline for maintenence or reinstalls or something, I'm over on the 486. Or, I pop the laptop section out if I want to write, so I can get comfy on the couch.

    So, I really don't have anything to add, just to point out that you don't even have to convert old 486s into routers or something - they can do basic computer tasks just fine on their own. I can't play Quake on mine, but I can do everything else.

    I remember working at a Pace Membership Warehouse (eventually bought out by Walmart/Sam's Club) as a forklift driver and having to constantly go over to the Electronics Dept. to help with computer sales customer service because it was said "You know about computers and stuff, answer their questions".

    I tried several times to explain the processor differences to people buying computers; 486 ....SL, SX, DX, DX2, DX4 , we had computers based on each cpu displayed, and I would inevitably be led into "tech debates" with uninformed customers.

    I once had a guy argue with me that a DX2 meant that there were two processors. I tried, courteously, to explan that was not the case, and eventually decided to walk away and let the sales worker handle the man.

    The sales guy assured the customer that he was correct, that the DX2 did designate a dual processor mobo.

    Ironic twist: The man returned with the computer a couple of months later and claimed the sales guy lied to him, that the computer in fact, did only have ONE cpu. I didn't gloat, but I thought what a moron. I mentioned to the returns staff the context of the sale and the customer's request to return the computer was rejected.
