... in the meantime ... I created an external EPROM interface for the 128 KB EPROMs and indeed it works as a halfbank filled with Turbo-C executables. Next experiment will be a fullbank 256 KB package spread over 2 chips.

Small UV-erasable EPROMS in the PLCC-32 case seem to be unobtainable, so one would probabaly have to switch to a similar Flash ROM for a smaller package.
