I received the computer today.
The mainboard is a 1248 Rev H.
I have backed up the two EPROMs, the character ROM is good and RTC is reporting it as charrom.bin Microbee 128k Standard.
The other ROM it can't identify as by it's checksum, but looking at the ROM dump as ASCI I can see it says 'MicroBee Disk Monitor c1983' the same as the 56kb.rom, but has a different checksum, so either its a different revision of the ROM or it has some data corruption in it as it didn't have a sticker over the window on the EPROM when I got it.
So from what I can gather my computer is in a 16Kbit case, but is a 64K model with the MB1217 colour board fitted.
Can anyone add anything else?
