Maybe I'll trace out the keyboard schematic (or at least as much as I
need) - it's just occurred to me that maybe the keyboard was shipped as
a completed unit (with the handful of ICs in place) which is why
schematics for it seem to be lacking...

Does anyone have the pinouts of the Nascom 2 keyboard connector
handy?
I'm wondering if there are any duplicated ground lines such that I
can
get away with running a cable via DA15 connectors
(the connectors on
the
'2 and keyboard PCBs are 16 pin headers)
Mine's not handy, but it does in fact have a DA15 plug on the keyboard
and a DA15 socket on the Nascom chassis. So although I can't tell you
which line to drop, it would seem it is possible to do so.
