I'd just the same idea when I saw the stimulus capabilties in gpsim.
But we'll need external hardware for the port to get more than 8 outputs

and 4 inputs, at least if a port is bidirectional we'll need a tristate
buffer.

Does anybody know a PLD which can be programmed in system, (EEPROM- |
FLASH-able)
to have the possibility to reconfigure the PORT-Layout. Using a PIC16x84
directly would be
to slow, because there is the communication with the host.

(What to do with the AD-conversion of 16C71, using the Soundblaster ?)
