National made an MM5203 that was also 256-bytes in
size and was also
difficult
to program. It was an even more suitable part for
jewelry, as it had a gold
flash all over its upper surface. It was quite a striking piece of hardware
with its large gold surface and extra thick quartz window glued to the top.
Ditto the 5204, which PTC used in the first SOL personalty modules...
