IMHO the block diagram is correct, so I only can think you misunderstood
something. What crossed my mind is, this OZ-card is NOT the project called
"PC-card". The "PC-card" is a C64/128 interface to emulate a ISA-bus, the
OZ-card is a PC-interface with several functions:
1) emulating a processor
2) Real time debugge / logic analyser
3) emulating a cartridge

The two blocks, "Processor version" and "Cartridge" (forgot "version"),
represent an OR/OR situation. Either the PC-interface is connected to the
socket of the processor (and replacing it), or it is connected to the
expansion slot.

The text above is not the initial version. I think the confusion rised
because of using the word "PC-card" as name for a project, and the other
time as means to tell this is a card you plug into the slot of a PC.

Groetjes, Ruud
