If the AGA chipset is put on an FPGA based accelerator board, 95% of the original OCS/ECS chipset becomes useless (16-bit Chip RAM is too slow for AGA DMAs).
Only the I/O related chips stay a little bit useful on the A500/A2000 PCB :
- Paula (Serial port, Joystick/Mouse)
- 8520s (Floppy, Parallel port, Joystick/Mouse, Keyboard)
