The IIc prototype that I have must be a later revision, since it has a
mask-programmed character ROM (that is marked as a prototype) instead of
the EPROM that is in your machine. It has been a while since I've had it
apart, but I seem to remember seeing several other (non-ROM) ICs that were
labeled as prototypes, as well. I'll open it up again and take a look.

If anyone is interested, there is a fuzzy picture of this machine on my
(currently content-poor) collection web site, at
