I'm curious about one thing... would it be possible to use TobiFlex 68k core instead of the real 68000? Would the design allow 24bit output if it was updated to AGA later? What about extra memory... adding 16MB would increase the cost much?
I ask these questions because I've seen Tobiflex core reaching reaching a 42Mhz 68000 in benchmarks and perhaps in the future someone adds support for AGA, 020, fast memory or uses the extra memory to emulate other machines.
Hello,
I have done a study on this kind of design already, here are the main components:
- Cyclone III EP3C25
- SDRAM 16MB (chip)
- SDRAM 64MB (fast)
- VGA DAC AD725
- Audio DAC PCM1742
- AT91SAM replacing the PIC.
BOM price : $100
PCB price : $40 (for 10 PCBs)
BTW, 16MB of SDRAM (Samsung) costs $1.35, really cheap :-o

Frederic
