As a method of connecting a custom SIMM memory tester and an IBM PC I'm
considering using a PIO24 I/O board to implement a parallel
bidirectional data bus w/control lines.

Researching this issue, I considered using ECP or EPP instead. The
obvious advantage is the ability to move from one host to another
without having to open the case.

ECP is too complicated for this application. Does anyone have any
information on EPP? 8 Bit bidirectional data transfer under host control
would be ideal. Is EPP appropriate? Is EPP the same as the bidirectional
mode available on PS/2 printer ports?

I didn't find exactly what I needed on the web.

Thanks for any thoughts on this one...
