This is the technical manual for the old original IBM PC. Schematics start on page 465. Page 475 shows the ISA connectors. Data buss, address buss, clock, hardware IRQ lines, etc. Pretty basic stuff, bare bones.
I still have one of those old manuals around here somewhere. Old tech sheets make me kind of sentimental, I guess that makes me a real geek.
I have a lot of 1970's computer magazines too, mostly about 6502 processors like the Apple II used. Back then, the magazines were mostly about hardware and showed schematics. Software was usually little snippets of machine code, or sometimes stuff written in 8K BASIC.
