Just out of curiousity - since you mentioned the chip-plots
for the TIA, did you ever run across the schematics for the
TIA? Besides being interesting to look at, it would:
A) Be valuable as a reference for emulator writers
B) Allow someone else to clone the chip someday, using '90s
technology - complete with all quirks of the original.
C) Illuminate the reasons for some of the quirk's - like the
"Cosmic Ark" Stars effect.
D) Possibly uncover other quirks/features, which may yet lie
undiscovered, to be used in new games :)
