WOW!
someone spent alot of time reverse engineering the hhc and i thank you.
That 'someone' is on this list :-)
i downloaded the schematics.
so far i have a lead on a 1400 hhc which should be of use for the
programmer or just a display board swap.
Waht exactly is the fuatl weit hthe exising one? Mising columns? Missing
rows (over part of the displau?) Odd dots missing?
anyone know if the tv adaptor has a rom in it?
if not, it could be built of some perfboard if the chips are still available.
The only HHC peripheral I ahve seen is the printer/cassette interface and
tht contains a ROM and a custom I/O chip. I would be very suprisied if
the display interface was all standard ICs.
