This was my idea too :) 65C02 can be safely used, AFAIK 65C102 and 65C02 are compatible from the software side. What I thought is to use a 65816 CPU instead. CLCD ROMs seem not use bit ops of 'C02 which are not on 65816 (SMB/RMB? and like). But then you would have a "16 bit native mode" (probably with the ability to set the clock to higher frequency as well) of your "CLCD" capable of addressing more memory etc, but still being compatible with CLCD. Maybe the only headache is to create the LCD controller and MMU, I guess some kind of CPLD or FPGA would be needed, but I am really not the right person about those PLD topics anyway. If the machine has some eg SPI interface built-in it can be even used for "serious work" eg programming AVRs, using it as a serial terminal and so on. Especially if it's packages like a real CLCD so it's easily portable and has batteries. Much better feeling than a PC notebook :) :) Message was sent through the cbm-hackers mailing listReceived on 2014-01-22 09:00:02
