The Options and Adapters Techref includes a section on the IBM PC
Prototyping card (and the PC/AT update for the O&A Techref includes a
secion on the 16-bit bus version of that prototyping card).

These cards had the bus buffers and address decoder already on the card,
linked up by PCB etch (a schematic is in the techref, of course). And a
large wire-wrap area for your own stuff.

IBM clearly thought that some users would want to build custom interfaces.
