I've been thinking recently about the technical feasability of somebody making a new retrocomputing platform aimed at hobbyists.
Specifically I've been wondering if it would be possible to design a system based on 8-bit era technology that had both a MOS 6502 and a Zilog Z80, but without crippling either processor.
Usually when I bring up this topic people just say "The Commodore 128 did that decades ago" and that's the end of the conversation. But the Z80 on that system was severely crippled and it seems to have never been used for anything other than running CP/M slowly, even though it has access to almost the entirety of the machine hardware.
Anyway that the background. But I'm not sure if:
- Questions about designing such a system would be on topic here.
- Whether questions would even be possible that are not "too broad".
- If users of this website would even be interested.
This is not about any other feasability concerns other than the technical ones so please don't bring them up. Please also don't bring up that there are many emulators. You can bring FPGA as long as it would implement a system also technically buildable in real retro components.
Anyway, if point 1 and point 3 are in fact OK here, I'm interested in thoughts regarding point 2.
