Great. :-) My available technical documentation essentially ends with the
enhanced IIe. I can count on zero fingers the number of tech ref manuals
that I've got for the IIc (Plus) and IIgs. But I've got user documentation
for those two machines. How helpful!

Yeah, I saw that when I used the Slot Scan 1.62 program, the FocusDrive was
identified as SmartPort Device (Error #39).

By the way, does anyone know what Error #39 means? It's come up in this
group before, and also with a FocusDrive, but it was never explained.
