Very interesting. And nice to hear, that another QL hardware designer has appeared. Just a little hint: What you are going to do, overlaps a lot with work that had already been done. E.g. the Aurora is a QL compatible mainboard (without the CPU/RAM part) with QL extension bus. The Q40/Q60 are complete QL replacements, with ISA-style extension bus. I gather you want a single-board system, but is that worth re-inventing the wheel? How about an Ethernet/USB/whatever-you-like add-on for existing hardware instead of a completely new mainboard design? If it makes good sense to put your add-ons onto the same board with existing stuff, that could still be done later on. That's just a little though. I don't mean to corrupt your ideas. Please design whatever you like :-) All the best Peter
