Getting a Classic PC Working After 25 Years?

tunersedge writes "Yesterday I dug out of my parents' basement a PC they had bought brand new in 1984: Epson Equity I personal computer; 512K RAM; 82-key keyboard; 2 (count 'em!, 2) 5.25" floppy disk drives; 13' RGB monitor (with contrast/brightness knobs); handy on/off switch; healthy 25-year-old yellowed plastic; absolutely no software. (My mom ran a pre-school, and they used it to keep records and payroll. I cut my programming teeth on this thing. GW-Basic was my friend. Kings Quest screens took 2 minutes to load when you walked into a new one.) When I resurrected this machine I pulled the case off, dusted out a little, and plugged it in. It actually fired up! I'm stoked, except the disks we had are missing. What I'm looking to do is either buy some old working disks with whatever I can find (MS-DOS 3.22, GW-Basic, whatever), or try and recreate some using a USB-based floppy drive and some modern software. Has anyone tried to resurrect a PC this old before?"

      I've used a couple models of Epson Equity. The custom DOS version 3.2 on the XT model (Equity I) is easy to find online, but there's really nothing special about it. The AT model (Equity III) had DOS 4.01 and it was a generic version.

      MS-DOS 3.3 is probably the easiest to find and is the ideal version for an XT-class system. A full 3.3 will have GW-BASIC on disk 2.

      -uso.

    FreeDOS probably would boot on this machine.

    I actually know the machine you're talking about - except I had a HDD. I know for a fact the thing will run MS-DOS 5.0.x

  3. Watch out on the usb floppy.. by tuorum · · Score: 4, Informative

    Thought they make them, they are probably all 1.2MB ones, which use a much smaller write head and might not be easily readable on the old 360KB drives. YMMV and it can't hurt to test. Good luck!

      Right. However, creating 360k disks in a 1.2MB drive may not be easily readable by an actual 360k drive due to the different read/write head sizes between the two. The smaller head on the 1.2 doesn't have a problem with the wider tracks of the 360k, but the other way around is know to cause issues.

      Just a thought - unless I'm mistaken, the floppy cable that plugs into a 3.5" drive also fits in a 5.25" drive - and the power connector for regular PATA hard drives also fits the 5.25" floppy drive. If that is still the case, all he needs to do is put his old 5.25" drive next to a new computer, plug in the cables and fire it up. Create a boot floppy using the Windows 95 'create a boot floppy' utility or however you make boot floppys now (I have a .img file of that boot floppy I use to create boot CDs, so it's been a while since I made a boot floppy - format a: /s maybe?)

      Put the 5.25" drive and your new boot floppy back in and Voila! you are all set.

    I used to do this all the time with game companies back in the nineties. Often times they'd send me free copies of their C-64 programs and whatnot. It is absolutely worth a shot even though nowadays the operator on the phone is probably not going to even understand your request and/or believe that such a product ever existed.

  8. Awesome find!!! Here's some software suggestions. by samalex01 · · Score: 5, Informative

    Hi!

    What an awesome find! You can actually download all the software you'd ever want for the system here - http://www.vetusware.com/ - which is a website with hundreds of abandoned software titles for download free. They do have various versions of MS-DOS, which I'd suggest MS-DOS 5.0 or higher because I still have nightmares of edlin *cringe*. They do have MS-DOS 6.22 for download along with GWBasic, QBasic, Borland C++ for DOS, etc for development. I assume since you said the system is from 1984 that's it's an 8086 or 8088 which rules out Windows 3.x.

    After years of using TRS-80 systems I moved to an 8088 XT clone in 1990 running MS-DOS 3.3, and as you that's where I really started learning to code with GWBasic. About 6 years ago I had some stuff in my closet shift one evening and that old system fell from the top shelf to the floor never to boot again. I wish I still had it, but a few years ago I did pull out an old 486SX system I picked up used in college (around 1996) and played with some of these old DOS languages and games.

    Have fun though... so many people cast away these old systems as boat anchors, but they're awesome to work with if you have some patience.

    You need to upgrade the RAM to 640 KB. Generally Radio Shack has some SIPPs you can add to the motherboard to add the last 128 KB.

    You will need to find a Double density 3.5 floppy drive with a Card edge adaptor. This will allow you to use double density 3.5 floppies in the computer. (High Density will not work.)

    You can network this be getting an 8-bit NIC that has a BNC and AUI port, then adding an AUI to UTP tranciever, but you can't use DHCP with it. The WATTCP stack for Dos will require a static IP.

    If the video card is in an ISA slot, (and some times even it it isn't.) get a 16 bit ISA Trident VGA Card. This will give you VGA, EGA and CGA support. You can then plug the Computer into a standard monitor.

    Okay, this may not help but then again it might...

    I dug up an old Laser 128 (Apple II compatible) with no working software and was able to get it working using the following method. I don't know if your machine has a compatible feature, though.

    http://adtpro.sourceforge.net/bootstrap.html#Starting_from_bare_metal

    In short: using a second machine (In my case, running Win98) and a homebrew serial cable, configure the machine to be revived to treat serial port input as keyboard input, then keyboard input direct into memory (like a DEBUG prompt) - If you can do that then the rest of the procedure might actually work with compatible software.

    The support machine "types" the software directly into the host machine's memory and executes it. In the link above, you start with a ProDOS image which then gets written to disk so you can boot the machine normally.
