Hi Everyone,
I suppose this is off topic but I had a retarded thought.
How about getting some sli like action going? Make a custom circuit to plug into the Denise socket that reads the incoming signals then splits the display jobs in two, sending maybe the 0-5 bitplane graphics to a Denise and the 6-11 bitplanes into another Denise. Then wire the resulting graphics to the video hybrid (Resistor network) through the socket. This probably wouldn't allow more chipram but the display refresh could be faster and maybe compatible with everything.
Regards
John
