I don't know about obtaining them, but I do have a small supply of PC/XT
keyboards and XT<->AT switchable keyboards. I have a stack of original
IBM brand PC/XT keyboards that would be nice except for the fact that
the layout is rather odd. I believe there's a backslash key ('\') where
left shift ought to be. I have other XT compatible keyboards that
conform to the AT layout we've all become accustomed to. Shipping to
Australia from Kansas would probably be prohibitive, but I haven't
looked into it.
Most, if not all x86 PCs have an 8042 microcontroller for a keyboard
decoder (or an embedded equivalent in the chipset) so they're pretty
well hard-coded to work with XT or AT keyboards. But the MM/1 uses a
UART and software. I believe the hardware is capable of communicating
with an AT / PS/2 keyboard -- someone just needs to write an appropriate
