I bought this computer along with some other 'stuff' - old CDs, AOL discs, SoundBlaster box from Circuit City....
The PS/2 is a model 25. The various stickers fell off of the interior while checking the disk connections. Ultimately the 20mb hdd was deemed a goner - I'm sure I could follow a guide to fix it, but instead I went with a CF card ISA adapter (CF uses ATA protocol - I didn't know this before my adventure!).
I ordered the 8087 co-processor along with the ISA adapter for the vast improvement it offered to Pac-Man. I highly recommend Monotech Vintage PC. It's a long shipping distance to the US but totally worth the wait.
I write on it using WordStar, a word processor I began using in 1989 or so when I had to write a state report on Indiana. Back then I was using an XT clone running CPM/80.
Lol love this
