Good point. What about a card that can can switch to a different 8 bit system such as Commodore 64, MSX, and so on emulated by the FPGA hardware? The card also have ports to use the pepherials of that system such as disk drive, joystick etc. The video and audio output also comes from the card for better performance. This way we have ALL the 8 bit system in one and in the case of the AIIGS.
This is the ultimate aim of the Replay platform. C64, MSX, Spectrum, BBC B and various others are all more or less working and waiting for the system software to be stable.
The daughterboards concept allows for anybody to design a peripheral - I have some with just 0.1" patch available, and 3V3 protection buffers.
