    AMD also made a 386SX-40. Despite having a tiny "Designed for Microsoft Windows" logo printed on it, it easily got bogged down by larger Windows 3.x applications, and the matching 387SX-40 math co-processor was difficult to find.

    My first serious job, back around 1993, was building beige boxes for a local computer store, and I put together a lot of these Am386 machines, which were a good deal cheaper than i486 and Pentium boxes, and since MS-DOS 6.22 with Windows 3.11 was the standard OS setup, the Am386 was able to run just about everything you could throw at it (well, maybe Doom was a bit slow on it). Also, it was the box I first tried out Linux on -- Slackware 2 on 73 floppies!

    I remember my Gateway 2000 486DX2-50 had a 6v battery connected to the board via that 4 pin connection you mentioned. When that battery failed I got myself a 4AA battery holder, and threw four alkaline AA batteries, and it was happy again.

    Man....this vid brings back old memories of the bad ol' days when you had to enter # of cylinders, etc to get the hard drive to work. Had to set IRQs on add-on cards or on the motherboard to get peripherals to work...etc.......ahh...memories! Great vid! Just subscribed to your channel! :)

    Woah, flashback. Our first semi modern computer we owned in the 1990's used that same case. I wish I still had that computer.

  • @gbowne1
    @gbowne1 12 років тому

    I used to love that case.. back when I had my 386 and 486.. but I eventually bought the full height tower version. The computer I had that was just like this one, It ran my BBS.. back when people still did those things pre-1995 internet/web.

    I had that CPU as well when I was young, though it was a different motherboard, PC Chips if I recall correctly.
    That was the first computer I ever took apart
    I actually did install windows 95A once I upgraded the ram to 20mb, and yeah, it took 7 minutes to boot lol
    I also had an ATI Stereo F/X sound card in there, I'm regretting so much not keeping that one.
    Thanks for the great video and the memories ! :)

    I too had a AMD 386 40mhz system very similar to the one in your overview. It was branded as Magitronic. I even remember using a Magitronic 13" VGA monitor with it as well. The performance was excellent and would beat most low end 486s of the day. Windows for Workgroups (3.11) ran very nicely. This system, paired with a Gravis Ultrasnd, was gaming goodness.

    wow a blast from the past, i had soo much fun on my old machines :-)
    286/386/486 machines were great fun, i used to force bigger cache chips into mine and the maths co pro, even the ancent mfm hdd cards would work :-)
    I bunged a plastic holder in mine with nicads in, did the job fine.
    And because my machines were often bust castoffs, my memory strips were often held upright with wooden washing line pegs with hacksawed slots for the memory, yes i was a git but i didnt break the clips!!

  • @Jerkwad152
    @Jerkwad152 12 років тому

    There were a few late 386 boards that could take either a 386 or a 486 chip, and had VESA slots. Most of them came with a 40MHz Cyrix 486-DLC, which is a hotted-up 386. It took the 66MHz 486 DX/2 to beat that chip.

  • @Behemothtek
    @Behemothtek 13 років тому

    Used to have the AMD 386 SX 33 version of this, was a quick chip for the price. I seem to remember we later upgraded to a 486 SX25 which we could over clock to 40 MHz.
    AMD did in fact produce a 486 CPU which ran at from what I remember 133 MHz and we got ours to overclock and be stable at 166.

  • @rwg520

    I just found one of these in my basement yesterday! I bought it new in 1993 for my wife. We moved in 1998 so I thought it didn't make it into the new house for some reason. Anyhoo, the case looks almost like yours but has a numerical digital readout for the standard speed 20mhz and turbo 40mhz (with the AMD 386 chip). Mine has the Acer ALi M1419 mobo (KMC-A419-8) It is VERY similar to the BioTeq board. My battery is still good and taking a charge! However, I have the ext. battery header, so I'm going to use it with 2 CR2032 batteries, and yank out the old one, as they are ticking time bombs as you mentioned. I really liked your description of everything, it helped me understand some things I didn't even know when I bought it new from Micro Experts. It still has Windows 3.1 and DOS 5. It has 4 MB of RAM (which I shall soon be upgrading) and a 100 MB hdd, which I shall also be upgrading. Still has all of our old programs, games and other personal info. I am AMAZED that it still functions perfectly after just sitting for about 16 yrs!

    I never seen a 386 machine with 72pins memory and vlb. On the 486 you get vesa local bus and later pci. And with the 486 platform you get the first 72pins simms. My favorite bus for a 486 is eisa. I had a compaq server with 2 3com eisa nics and eisa video and eisa scsi card. i ran windows nt4.0 and linux redhat 6.2 on it. good old days

  • @vwestlife
    @vwestlife 13 років тому

    You've been messing around with PS/2s too much. :-P Aftermarket 386 motherboards with Local Bus slots and/or 72-pin SIMM sockets were extremely rare, and most that do exist are actually "386/486" boards, designed to let you start out with a 386DX CPU and then upgrade to a 486SX or 486DX later. Alternatively, these boards would've already come with a 486SLC, 486DLC, or "Blue Lightning" chip, allowing them to be sold as low-end "486-class" boards even though the underlying hardware was 386-based.

    I remember pulling a 3.0 GB hard drive out of one of these dead systems (battery destroyed all the important traces, acid was everywhere) and when I put it into my Pentium III PC (Compaq deskpro EN) and it took 3 minutes to get through boot because of all the new devices, and a extra 20 to install those devices.

  • @Jerkwad152
    @Jerkwad152 13 років тому

    Also, (sorry for the triple-post), I've got two 486 boards with bugs that make them y2k incompatible. They'll let you set the date well enough, but the moment you exit the BIOS setup, the date will change to 2094. I managed to find a DOS TSR called y2kure that fixes that on bootup. It seems quite a few later 486 boards with the Award Modular BIOS had that bug.

  • @muchosa1
    @muchosa1 13 років тому

    Yes pre plug-n-play was a big hassle. I used to use internal modems because they where cheaper but always had issue with IRQ's and address spaces, so I finally went to external modems so I wouldn't have to deal with it.

    Cyrix had a harder time than most. They didn't have their own production facilities, so they had to lease them from TI and SGS-Thompson. Obviously they ended up with the out-of-date equipment. Notice after they started working with IBM and got the state of the art facilities, the 5x86 and 6x86 came out, and were really good chips. I've got one of each, though the 6x86 is marked MII(same thing).

    The Amiga collectors know all about the battery problem and have come up with a battery hack, which is a coin battery holder with a simple diode to keep the charging circuit at bay. A variety of (Amiga) retailers make and sell these battery hacks (which are made to fit perfectly on the motherboard), but they are cheap and simple to make.

  • @Aeduo

    A lot of the fear of the Y2K bug wasn't so much in home desktop PCs, but in stuff like banks and businesses or government/military where they used (and often times still use) very very old 60s and 70s mainframe computers.

  • @Jerkwad152
    @Jerkwad152 13 років тому

    AMD didn't make a 386 faster than 40MHz. However, IBM did make a triple-clocked version at 75MHz, which they called the "Blue Lightning".

    Speaking of HDD geometry limitations, my Time Machine PC running on the Abit AB-TX5 board is limited to 32GB, but when I installed both MS-DOS and Windows XP on a 200GB HDD, DOS saw only 7.8GB, so the options I had was to either get a Hard Drive with a jumper for a 32GB limitation (I have a 40GB HDD from a Compaq Presario 6300us now with a 120GB SSD connected to a SATA PCI card) or use Ontrack Dynamic Disc Overlay (took about 2KB Conventional Memory away in DOS), so both options worked surprisingly well. Now it's time to try to install an SSD in the Time Machine.

    I had a motherboard with a 286 AMD CPU in a digital Venturis 466, but the tranformer blow the i.Chips right off the motherboard, and smoked all the i.Chips sets. I still have the DEC Venturis 466 computer case, still looking for an old 286 AMD Motherboard for it. I have 5 old 486 computer cases, and many 486 replacement motherboards yet, plus a few 386 motherboards ! The best 386 I owned was a (NCR PC 386 sx) computer case---I still have the two sticks of memory from off of the 386 motherboard. The CMOs on the 386 became corrupted from my friend flashing the cmos wrong ! I love old 286/386/486/ & Pentium 1s/ Pentium 2/ Pentium 4 ! My favourite was the old Pentium Pro in the old Dell computer boxs. I found an old DEC Celebris (2600 ? or 3600 ?) down along the street corner with a Pentium Pro inside on the motherboard. The DEC computer case was missing the harddrive, and transformer but everything else was still intacted.

    Motherboards up to late 386 early 486 boards had a jumper to select color and monochrome monitors with any video adapter in place. I actually found a 386 board that can run a processor up to 40MHz which is a removal processor (Socket type CPU), external battery jumper, and a jumper to select between 3.7V and 6V for the external battery. The issues are i don't have an ISA VGA card, I/O card, a serial mouse, keyboard (might purchase a PS/2 to AT keyboard adapter since I have a keyboard I might use from my server), and a case/PSU combo for the parts ATM. And I was thinking of making a 386 computer to run games that require up to a 386 CPU since they either run too fast on my K6-2 computer, or I get Exc. Checksum errors on my Roland MT-32 since the K6-2 is an equivalent to the Pentium II CPUs.

    Those Ni-Cds were leaking way back in 1998 on 386/486 machines as I had to replace a few. They are the #1 killer of Amigas it seems. That Leading Edge board really isn't worth saving and likely died from other causes (used to service alot of their equipment). The Model D3 wasn't all that special or reliable.

    They're pretty much identical, though the brand name escapes me at the moment. The CPUs are socketed rather than soldered, though. And both of them had those nasty nickel cadmium batteries, too. First thing I did was desolder those things and put coin cell holders in. They haven't had an issue since then. And...I have that same Trident VGA card! It gets the job done.

    Take a piece of cloth, soak it in Vinegar and place it on the rust spot for a few days (re-wetting it as needed) and it will come right off. Another way is to take some aluminum foil and ball it up and rub it on the rust and it will also come right up without scratching or otherwise damaging the surface.

    If the battery is less than 3v you should be able to use a CR2032 with a diode to prevent the motherboard from trying to charge it. CR2032 don't ever seem to leak, they just run out of charge, and they have good storage life.

    This could have had an EISA system bus rather than the standard 16 bit ISA slots. EISA was the rest of industry's answer to IBM's Micro Channel Architecture or MCA which was fast, plug and play that actually worked, but required a license from IBM and were expensive and really only found on IBM computers. EISA was an industry standard that was supported by the "Gang of 9" including Compaq and others and was in service well into the PCI era. I have a P200 with an EISA bus. Almost all servers used the EISA bus until the P-Pro came into wide spread use in Servers in the late 90s.

      If the 386 is "at" 50 MHz the system board is at that frequency to. There was no clock doubling on the 386. But perhaps you simply mean the 386 was specified for a maximum clock of 50 MHz?

    I actually did had one of those 133Mhx Am486 chips and yes i ran mine at 150mhz !!!! 50mhz x 3 !!! normal setting for the chip was 33 mhz x 4 it had the same performance as a Pentium 75 at the time. I could play the origional starcraft on it... Starcraft did not run on 486's if i can remember but i could because of the 150mhz AMD 486... hehehehe

    I've got two motherboard with that 40MHz AMD chip and either one of them would run Windows 95 just fine with enough RAM.

    You speak of Packard Bell PC's in America towards the end of the video and I've read something about that, but I know very little about it. I remember Packard Bell PC's being sold at Toys R Us of all places in 1996 when I was 12 or so, I thought Packard Bell was a cheap and nasty HP knock off brand, but then again I didn't know too much about computers back then, I believe in the late 90's I read an article about PB getting into trouble for using old recycled parts in newer computers.

    Wasn't there a lawsuit by Intel that delayed AMD's release of these 40MHz chips?

      +souta95 there was an attempt by intel to keep its advantage in the microprocessor manufacturing market, they refused to share any of the details about the 386 to amd, forcing them to 'clean room' design it, i.e reverse engineer it, which was perfectly legal because intel technically broke a prior agreement with amd to be a secondary producer of x86 processors.
      amd ended up winning the legal dispute.
      this is from memory, I could be wrong in some of the details.

    Probably so. I bet the BIOS still said 2094, until you got past the POST.
