There's a great book c. 1980 by Osbourne Press, "PET CBM and the
IEEE-488 Bus (GPIB)", Eugene and Jensen, C.W. Fisher, that focuses
on the Commodore implementation of the GPIB, but nonetheless, has
some good, basic, bit-level explanations of the GPIB.
There are some freeware products you can use to experiment with the
GPIB... VICE (a PET/C-64 emulator) is complete enough that you can
write programs to set talkers and listeners, and develop application
code in BASIC or assembler to "talk" to a Commodore device. If you
are trying to talk to, say, an HP GPIB disk drive, you'll only find
basic information, but it's a start.
