AFAIK, all are out of print, but IBM probably have some remaining stock of most of them. I bought several manuals about a year ago. The XT Model 286 manual is unavailable. The others that you might need are : PC XT and Portable PC AT AT suplement for the type 2 board (those contain schematics of the motherboard and keyboard, BIOS

Options and Adapters. 2 volumes covering just about every card for the

and XT, monitors, drives, etc. O&A AT update (16 bit cards, serial/parallel adapter, etc) Scientific O&A (GPIB, DAC, PGC, etc) PC-jr (PC-jr motherboard _and all option cards_ for it in one manual) I posted the forms numbers (which you need to get them from IBM) on

list a few months back - it's probably in the archives somewhere... They're not cheap, but not too expensive IMHO. Figure on \pounds 50.00 per volume. I was pleasantly supprised by the ammount of information

I got. -tony
