The Goupil G3 is a rare machine, here's preliminary emulation running the monitor:
It uses a serial connected ASCII keyboard but has some special keys, including one to boot floppy which I don't yet know what ASCII code it's supposed to return. I believe the machine is fully emulated, including floppy, but until I know the command to boot then I can't test FLEX and others.
I'm also trying to source another dump of the character ROM as the only current dump seems to have a few missing bits:
There are also other CPU cards for the G3 such as Z80 and 8088, but currently haven't had their ROMs dumped.
