I have a huge passion for Amstrad PCs and would love to see them emulated. The PC5286 was my childhood computer, and I recently bought a PC7486SLC33.

I have no idea how to submit patches that could make these possible in PCem, but just discovered the alternative of 86Box which seems more open to adding new machines on request, so I thought I'd try asking. :)

Bios dumps for the first two machines are here (hopefully they work!):
