FWIW, I've successfuly operated many (not all) Apple II cards at
the end of a 50-wire ribbon cable about 30" long.  No buffering or
crosstalk protection was required, and only the usual power bypassing
on the card itself.


Homemade version of the SCRG Extend-a-Slot?

Essentially.  The cable I used was actually a surplus cable
used in an older computer system (maybe an HP3000 ;-), with
three connectors as in the Apple II, and, at the other end
a 50-pin card-edge.

About as close to an Extend-a-Slot as you can get without
switches.  ;-)

I've also used an Extend-a-Slot with a printer card, a modem,
a Mockingboard, and something else I can't remember.  ;-)
