Ibm pcxt/at /clone schematic ?

[Lak]

I've googled around for a 640K xt schematic but found none.
Anybody can post one on the web ? (or clone -non copyright? )

thanks ..lak

ps.
I've got (all TTL design ) floppy,parallel,serial,cga and 256K pc xt clone schema on paper. Probably will scanned them if none exists on the web.

I think IBM published at least a partial schematic in the Technical Reference manuals for the PC/XT line, didn't they?

The technical reference for each machine usually had schematics of the motherboard and the major peripherals. For example, the PCjr Tech Ref has something like 40 pages (each one folding out to double size) of schematics in it.

Technical reference books/schemas are hard to find here ....in Singapore.
Most systems don't make it here in the 80's

Its just to complete the collection though it is simple enough to repair/maintain/modify those old xts computers without the schematics.
