mold? if its everywhere inside, good luck! if its just the foam, rip it out. use that armor all all-purpose cleaner. wont take the colour out and cleans good. the pinout is proprietary. this is a ps/2 remember? the form factor is not AT compatible, so forget it. model 60 is 10mhz 286 with 1 meg. there are chips to upgrade to 386 from 286, but only access up to 16meg anyway. 24bit mem addressing. the hard drive is esdi type which connects like an mfm drive. can't do ide drives either. i dont know of a mca ide card. maybe aftermarket though. i have os2 1.3 never used, but i'm keeping that for archives. david In a message dated 98-03-06 20:28:14 EST, you write: << I got a PS/2 Model 60 and OS/2 2.0 (1992, but still classic) PS/2: a)How do I get rid of the mold inside? b)What is the PSU pinout if I want to put in a regular motherboard? c)Is there a way to upgrade the mb to 386 with <$10 and a 386 mb OS/2: a)I installed it on a 386 w/4 MB RAM (min. requirement).
