Thanks Tony.
John D. emailed me and said he knows someone here in the US who might
have spares that we can borrow. I'll let you know how that goes (off-list).
That will be useful for testing, but presumably you will want to have something
of your own to keep on running the machine. By then I might have found all my
PERQ 1 bits (I did unpack the PERQ 2 keyboard, PERQ 3A mouse and all the
cabling today - NEVER move house unless you have to!) so will be able to
provide wirelists of the cabling, etc.
