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.
