I'm in no hurry. Thanks for the offer, but you
just finished
supplying me with all that documentation on the C4P.
You never updated me on that, how's it going?
The small daughter board contains three 2716s labeled
"REV 94 I", "REV 94 II", and "REV 94 III".
I think that's an Aardvark board too... no idea what's on the
EPROMs though...
Looking closer, there are sockets on the mother board for 8 pairs
of 2114s. There is one pair of 2114s in the first pair of sockets
and one pair of 2114s in the last pair of sockets. It looks like
the select lines for the 6 pairs of sockets inbetween are wired
to these 2716s. So it has the feel of some kind if firmware
application.
Hmmm... not Aardvark then. Those pairs of 2114s increase in address
from the edge of the board to the center. So he's
mapping those EPROMs
into addresses 0x0400 to 0x17FF. Since it seems he didn't
want to mess
with the BASIC in ROM on the main board, it might be that the 2716s
have some sort of BASIC program in them.
