- Actually, it's not that difficult to make an Amiga Parallel port work as
- an HP-IB listen only interface. I happen to have a schematic drawing for
- just such a device sitting in front of me. The interface uses an LS374
- and an LS240 chip to clock and invert the data lines, and two logic chips
- (74LS00 and 74LS11) connected to the appropriate lines to handle the
- clocking of the data lines and handle the reset and ack lines.
-
- If anyone is interested I could scan the schematic (currently it is a hand
- drawn schematic) and send it as an IFF file. If I get real ambitious I
- may even draw it up with a CAD program. Anyone interested?
-
- NOTE: standard disclaimer about not being responsible for any damages
- might result from anyone attempting to do anything as a result of
