  • Oh YEAH*! Another vintage computer to play with!
    This came from the same thrift store and recycling depot where I rescued the PS/2 Model 57SLC2 computer and Model M keyboard. In recent times they'd refused to sell me any computers, even with the under the table, cash-in-hand method I'd used before. I didn't expect just offering them $20** would have any chance of working! Wonders never cease.
    Though this didn't look too promising at first, with the case being incredibly greasy and the sound of something ratting around loose inside, a little cleaning and a new hard drive have this thing working great again. It is amazingly clean inside.
    Lots of people ask what I do with this stuff, and while I usually don't know for sure until I actually start doing something, I have got a plan for this system, involving OS/2. Right now it's running Windows for Workgroups 3.11 and MS-DOS 6.22 for testing purposes. When I actually get around to what I have in mind, there will be a video.
    Points of clarification: Cirrus Logic was not the first to produce a graphics accelerator for VGA/SVGA. I believe that honor actually goes to S3. Cirrus Logic was the first to produce a fully integrated, low cost SVGA graphics solution with a built in RAMDAC. To my great amazement, this computer's BIOS does support LBA translation for large hard drives, so the 1GB Seagate drive I put in works fine.
    There is 1 megabyte of video memory on this motherboard, thus making it possible to run in a high color video mode (16 bpp) at up 800x600 resolution. A lower color depth (256 colors, eventually dropping to 16) can be used at resolutions greater than 1024x768. HP (somewhat annoyingly) customized the video BIOS to output only certain refresh rates and to override refresh rate selection by most other software. The Cirrus CL-GD5428 chip is capable of any refresh rate that doesn't exceed its built in RAMDAC's specifications and bandwidth. I can't explain the strange video memory packaging, since 512 kilobyte ZIPs did exist. (I really expected that there might be 2 megabytes worth of video memory, although 1 megabyte was pretty darn luxurious at the time!)
    Cirrus Logic (and many others) left the graphics market during the early days of AGP graphics adapters, when the competition heated up, ultimately leaving just two big players, ATi and nVidia. I miss the days when there was actually competition in the graphics market. Rather than doing the right thing and keeping support for their former graphics products available, Cirrus Logic dumped all of that onto a company known as Integrated Software and Devices. ISD produced an embedded Linux product and was in turn swallowed up by the "Embedded Software Group". Somewhere along the line, everything pertaining to support for Cirrus Logic graphics products disappeared.
    The CL-GD542X series graphics ICs consume 1.5 watts of power at most. 1.5 *watts*. Compare that to modern graphics cards, which despite doing a lot more, also utilize power sufficient to run a small country. :-P
    I suspect that expansion slot artifact on the opposite side of the riser is possibly for a local bus video adapter or disk controller card. I don't know if such a thing was ever produced by HP, or if the slot was ever populated with its connector.
    One of the read/write heads inside the hard drive has clearly been "snagged" by something. There is also a totally unused platter in place on top of the active one. I've seen that before in Quantum hard drives...maybe it was a way to salvage what had been a larger capacity drive with a dead platter? It has no read or write heads extending to it.
    * It's probably sad just how stoked I am about this.
    ** It's a lot better than the 7¢ per pound that they usually get.

    The thrift stores I frequent do accept and sell computers, but the prices vary widely. One day you might find a nicely kept Dell Dimension Pentium 4 for $7.99 and the next day you might find no-name beige box Pentium-133 with missing parts for $29.99. Used LCD monitors are becoming more common, although most have scratched display panels, and the ones that require external power supplies are almost always missing them.

    Ahhh, feels good to hear your voice again, Bill! I really enjoy this video and I've always been a bit of a fan of the older Vectra machines. It *seems* in the rear where the ports are, a little piece of plastic actually telling you what each port does fell off. There's not much holding them on and hence why you have little bitty holes here and there in the back. Very great video as always!

    Boy, I sure commented a lot on this video in the past.
    I got ahold of a Vectra VE 5/120 series 3, and it seems that an artifact for a PCI slot would have been on the rear of the backplane underneath the hard disk. It's odd, I wonder if anything would happen had it been populated and had a card installed?

    We have Goodwill computer stores here in Calif, they only sell used working computers. Everything else however is just thrown out onto the shelves and you don't know if it works or not but you can return it and get store credit. I found some stereo receivers that were not working, showed them to the manager and offered to give them 30 or $35 for each, but they would not accept that, they wanted the sticker price.
    I argued that they are just going into the recycle bin but they didn't budge on the price.

    I don't know if you have covered the secondary memory in a later video, but the on board video memory look like the DIPs (dual inline package) memory chips. Those were used in a small window between direct memory DIMMs and ZIF sockets. These used a row of female sockets in the memory package and hard wired male pins upright on the motherboards.
    Good stuff, I think you and I think alike.

    My school was pretty awesome to me and I have gotten a few computers from them. An HP Vectra XM which shares this case style but was a little newer and an HP Vectra VLi8 mini tower which I still use daily with Windows 98 running on it. I was able to purchase a newer Pentium III 850MHz processor for it and surprisingly, the computer needed no DIP switch reconfiguration. It was listed to only support up to 550MHz but it recognizes the entire 850MHz, it's pretty sweet.

    Also, that hard drive really was knackered - it definitely had plenty of hours on it.

    I recently picked up an HP Vectra XM 5/133 system from my workplace. Took it home, works perfectly fine. That slot you mentioned on the reverse of the ISA expansion card, my XM has this populated and came with a 10/100 ethernet card. Unlike network interfaces today that have the 10/100, and even 1000 if you're lucky enough, are integrated into one port, this card has separate 10 and 100 ports. The card did function for a little while, however after a few reboots the BIOS started giving me "LAN error" warning messages so I decided to pull the card and install a spare gigabit ethernet card in to it so I can transfer data from my file server to it and vice versa. I know that the PCI slots it has won't be able to go that fast (heck the IDE channel probably can't even do 100Mbit/s) but it's what I had lying around. :p

    On another note, upgrading a 486 machine to a Pentium overdrive can be difficult because older 486 mobos have a 5 volt processor and socket. Therefore, the pentium overdrive is an 3.3volt processor, and though it could fit in the socket, the extra voltage would let the magic smoke out. Apparently you need a vrm modification to correct the voltage

    I have a similar computer but in an older revision acutally. Mine is the HP Vectra 486/33 VL. Yours has someking of COAST slot, but mine just uses regular sram chips. However mine is a socket 1 computer so this is not really good for upgrades ... but since this computer was given to us years ago (~15 years) and since I'm quite young for a retro computing enthusiast, as far as I can remember, to me that computer always existed, so I can't leave that computer even though it's not the best.
    It originaly came with a 486 DX33 with 8MB of ram, no cache, no expansion cards and a 170MB HDD. The HDD died unfortunately ... at some point I upgraded it to a 486DX2-66 CPU with 32MB of ram, a 10GB HDD, a sound blaster vibra CT4170 and I added a CD-drive (but it didn't have brackets so it was just hanging there and it didn't look good at all) but now that I have faster old computers, I put it back roughly to it's original specs ... though I made some other upgrades such as installing L2 cache, adding 512KB of VRAM for a total of 1MB and finally, I found a 270MB quantum HDD so it's close enough.
    I also installed a sound blaster pro 2 and a 3com etherlink III. For a "slow" 486, I'm actually quite proud of that computer ^^

No way would I ever tell them about it, because I'm sure they wouldn't take responsibility for not wiping their own stuff. They're in the business of spinning blame on others, so I'm sure they'd try to harass Goodwill over it.

(The computer I had planned to use for this demonstration needed to be cleaned up after a basement flood. I did that, but I haven't put it all the way back together.)

      @@uxwbillWell hey, more than anything, I just wanted you to know how formative of a memory this video is for me. I must’ve been in middle school at the latest when I watched it, and now I’m out of college and working as a systems administrator for a small company. Still into old PC stuff, too!

      I'm glad the video was a formative moment for you, and I also appreciate that you've been watching over the years. To try and give some sense of closure, while seeing how badly I remember what's in this video already...the story basically goes that external cache management on the Pentium Overdrive was a mess. Intel reportedly kept changing the specifications while manufacturers were bringing hardware to market.
      Write-through caching generally worked fine with the Pentium Overdrive. If your system supported and used write-back caching, that's where things could get really interesting. Some systems would run perfectly no matter how things were set up. Others were stable until you did some very specific thing and then the whole shebang fell down. The remainder of systems were unstable no matter what you did to try and get it working. You could see all of these outcomes even across multiple examples of the same hardware, with the same BIOS revision and the same software stack. I did! I had several identical "Lacuna" PS/2 Model 77 systems with POD CPU upgrades.
      Of these, one worked perfectly no matter what. The other would crash only running the reference disk or system configuration programs. I believe it failed with a "217" error code, which sometimes it would not do until after leaving the configuration programs and rebooting. The last example just crashed constantly if one dared to run a POD CPU and cache model in write-back mode. It was uselessly unstable.
      I believe I was going to demonstrate these on video, and compare them to an HP Vectra XA with a POD83 and 256KB write-back cache module.
      Could there have been some kind of difference in chip revisions that wasn't readily obvious? Absolutely. (I have a "Lacuna" board PS/2 Model 76 whose S3 graphics chip is marked as a prototype. That S3 graphics chip is also another case of a component being stitched into a design with a really hot needle. It was designed for VL-bus or PCI systems, but IBM put it in a Microchannel bus computer. Some of the resources used by that S3 chip also occupy those used by other hardware in the system, such as COM4. There were also timing problems that IBM tried to solve with numerous graphics driver releases, particularly under OS/2. They also tried different RAMDACs to resolve the issue.)
      While not really a fault, cache memories took on all manner of different package types and layouts...various vaguely SIMM shaped modules, plug in modules, and even loose chips for direct insertion to sockets. I'm sure some manufacturers did a better job of their board layouts, and that some cache controllers were better than others.
      I think that should cover it, unless of course, I've forgotten some detail or another. That's certainly possible.

      @@uxwbillThank you! I’m glad to finally know the story. :)
      I think I once tried to research the topic a bit myself, but finding any amount of useful info on the web, especially obscure content from decades ago, has become increasingly difficult lately. Your anecdotes are far more informative than most of the crap I tend to find on the web these days.

    I was about to ask if it was a Quantum hard drive based on what it sounded like but then the bit at the end came up... You know you've been messing with this stuff too long when you can recognise drives by the sounds they make.

    the hard drive sounds like the heads have touched on the platters causing a head crash and is not allowing it to run it's seek test properly, hence the drive powering on and off

      a password will not cause the drive to crash the heads on the media surface. thats a mechanical failure.
