Old PC stuff



I have a bunch of old DOS-based computers. They're fun.

Why bother? I don't know, why do people bother with old cars when newer ones are faster, better looking and more fuel efficient? There's something satisfying about getting an old piece of tech and making it chug along just right. And I also couldn't afford any of this shit when I was growing up in the 90s. Doom on a 386SX-20 is brutal in the most unfun way.

Pentium


Built to handle everything from 1994-1998ish. Might upgrade the CPU so I can play Mechwarrior 2 at a better frame rate. Has a spiffy little 233MHz CPU. Runs everything else flawlessly, including resource-intensive games like Quake and TIE Fighter.

386DX


Partially inspired by the "386 with modern parts" build by Phil's Computer Lab. I had a bunch of spare parts and wanted something that would run Wing Commander flawlessly. It's also a great box for Sierra/Lucasarts adventure games and EGA/VGA platformers. Runs most games from 1988-1993 perfectly.

Zeos 386SX-20


The first computer my family ever owned, a hand-me-down from my aunt. Was literally in pieces for years until I restored it to its former glory a year or two ago. The CPU and video card are pretty anemic, but otherwise the system had some pretty impressive specs for the time. I still have the original manuals & boxes for almost everything.

Turbo XT


Some of the first PC experiences I ever had were on my cousin's old XT clone PC. I think the hard drive and cards in the machine got shuffled around into newer machines over the years, but eventually ended up in a Samsung S330 XT clone. That machine acted funny in the last couple years of use (my uncle was STILL using this thing to do taxes up until 1998 or so) and when they finally upgraded to a 486DX2/66 machine they gave me this thing.

Unfortunately the system gave up the ghost not too long after that in multiple ways. First the Seagate MFM hard drive died. Thankfully I salvaged some personal family files from the disk before it completely failed. Next the CMOS battery exploded, corroding a huge section of the mainboard. Upon closer inspection, somebody had previously attempted to disable onboard video/peripheral components by physically clipping the SMD components on the board. Needless to say, the system was mostly toast. Somehow, the board still POSTs, but it cannot detect a keyboard.

I removed the remaining good components (EGA card, floppy controller, I/O board/MFM controller) and threw them into a generic Turbo XT computer I got from eBay along with a NOS MFM hard drive I got from someone selling them on the Vintage Computer forum. The machine runs very well now and can handle DOS games and programs from 1980-1992ish.
