Some simple graphics (the 4052 had write-thru) were indeed used on the
set, but I thought that these were generated by 4051's with the
write-thru modification, and 6800 machine code. I didn't know, though,
that the 4052 (which was MUCH faster than the 4051 due to a bit-slice
CPU that ran the Motrola 6800 instruction set) was used in Battlestar
Galactica. Could very well be, though. Jim knew his stuff -- the tapes
may well have been code for BG that ran on the 4052. The 4081 was a
completely different architecture than the 4051/4052/4054 -- no code
compatibility whatsoever. I also recall that 405x cartridge tapes
couldn't be read on the 4081, and vice-versa due to different tape
recording formats.

The 4052 I got from Jim Willing has a large collection of
tapes which he claimed contained BG graphics. I'll have to go
through them to see if any of them say anything about the 4081 on
them.
