    Default Zenith S100 board

    I have a Zenith 4-port serial board, which I believe might be a Z-204 Multiport Input/Output board for the Z100. Can anyone verify or otherwise identify it?

    The only technical information I was able to find on the Z-204 was in the manual for a Z-100 diagnostics program:

    Although the evidence based on references in that manual is indirect (ie the jumpers, and identity of the parallel ports at P106 and P107) it is consistent with this indeed being a Z-204 multiport I/O board.
