Hello all!
I have been searching the web looking for the original IBM PC/XT
schematics. I read on some post that they were published in the "IBM
Technical Reference Manual" and in the "Microcornucopia" magazine, but I
couldn't find it anywhere. Please, could you tell me where can I find
those schemes? Please, if anyone has it, can you make a scan and post
it?
Thank you.

until the PS/2 (real one from IBM, NOT SONY!), ALL of the IBM hardware
technical reference manuals had full schematics and source code for the

Not IN "Microcornucopia". Dave Thompson (the publisher) redrew the XT
schematics to combine the multiple pages into a single poster sized one,
that they sold. Because they were redrawn from the Tech Ref, any errors
in the original should be replicated.
One of my copies was sold along with the cabinet that it was taped to.
The other is unaccounted for.

Sony never made a PS/2, they only make a PS2 :-)
I think I heard that Sony has made something like 60 million of them,
now. Has that passed IBM PS/2 numbers yet?

Indeed the motherboard and keyboard schematics are in the IBM PC/XT (and
Portable PC) TechRef. The I/O cards, drives, monitors, etc are in early
versions of that manual, but later they were all moved into the Options
and Adapters TechRef.

I have a shelf of TechRefs (include the XT one), but no scanner :-(
