RE: Schematic for 80 Column Adapter for C64

I only know of one guy that might still have the equations in their raw
form as he was often the datakeeper of the department for anything he
worked on, and he worked on a lot of things.  So far he just laughs when I
ask to come over and dig through his pallets (yes he keeps them on
pallets) of CBM stuff. (initials FB)

If all of the schematic was there it should be straightforward to figure
the terms, we used PLA's instead of PAL's for jungle logic as we owned a
PLA core, got more pins out it and real PAL's were expensive ($1)  Only
the Z8000 was "approved" for PAL's back then.

OTOH it should be possible to reengineer the equations from the
schematics.
