Thanks Pete for your fast answer.
Yes it is a BASIC 4 Machine with these 4116-4 RAMs.
You wrote the correct substitute for the ROM chips are
Texas Instruments TMS2532 or equivalent. Is this right for
all the chips I will list below? I hope the TMS2532 are
easy to purchase here in Austria. Looking through my
little library I found the datasheet (at least a good
start) but I couldn't find a refence for substitutes - do
there exist any? Are the TMS2532 fully Pin-compatible with
the MOS ones? And my last question: Do I need anything
special to write these chips? I'd put together a little
circuit to hook on my Pc's Parallel-Port (this would be
the easiest way for me). I'm already googling for
information, but would be very glad of some links to
schematics and software.
Best regards,
Wolfgang
