Although some of the clone cards with a 765 and that little 8 pin data 
separator chip (9216 IIRC) were also very hackable.

Depends on what you mean by 'complete'. I have : 

PC
PC/XT and Portable
AT (with the update for the 8MHz board, later BIOS, etc), it ended up in 
2 binders)

These are the later manuals covering just the mainboard, keyboard, PSU. 

But then I also have :

Options and Adapters (2 volumes) covering the cards, monitors, drives for 
the PC and XT

AT supplement for the O&A manual

Scinetific Options and Adapters (GPIB, data aquisition, Professional 
graphics)

EGA Techref

PCjr Trechref 

All the above are real manauls with schematics, BIOS listings, etc in them.

PS/2 Hardware Interface Techref -- no scheamtics, no source code, but 
better than nothing. It was given to me by a firend, so I am not going to 
complain.

I also have the Hardware Maintenance and Service manaul for the AT. It's 
a boardswapper guid, but it was given to me (I bought the AT Techref 
second-hand, it came with it). It actually has some useful info on 
repairing the 5152 printer (== Epson MX80, basically).

I don't have all the O&A suplements, and I don't have the XT/286 techref, 
although that machine is pretty close the AT in hardware.
