You mean as in "keyboard"? Boy, there have

variations, haven't there? My most/least (love-hate) favorite was an
EBCDIC keyboard with individual enclosed dry reed switches for each
key (it was a George Risk model). A couple of Fairchild RTL ICs,
mostly a diode encoder matrix. Diecast housing.
I used it for a time with my TV Typewriter--the control keys were set
to impose a higher resistance force than the others (remember the
Beehive Super Bee?). It would make you very tired using it for
extended periods.
Does anyone have any idea what this may have belonged to?
I'm just kind of vamping here, but it sounds like the keyboard on
the standard main terminal for an RCA Spectra 70... Is there a larger
than usual "step" between rows of keys?
