I've recently heard of an archaic IBM device...a
10 x 15
array of switches, essentially a Big Keyboard, with
customisable plastic overlay 'keycaps'.
I have a device like this, taken from IIRC an NCR device ca. 1960.
It is definitely a keyboard and it contains a matrix of something like
(3x8=)24 by 24 switches, and it is coded, perhaps BCD. Underneath it
is all hand strung wires. I can dust it off and send photographs if
you're interested.
BTW, I'm *still* engaged in a probably-hopeless
search for
a ...console to use with my 1800.
1401 I've heard of. What's an 1800?
