Hey all,
I was wondering if anyone knows what system either of these two keyboards
came from:
1) APL keyboard made by Maxi-switch, IC date codes in 1976, p/n 2129-009,
keyboard encoder has "NKBD-452 03-004-05":

2) Keyboard branded as Licon 55-500129, IC date codes in 1973 and '74. Has
three blank white keys, one blank gray key, and one blank black key, also
"home mem", "marg set" and "video rvs":

I picked up both hoping that at least one would be simple parallel output
and so useful for homebrew stuff, but I am curious about what they
originally came from.
cheers
