Yup, the ASCII control codes on the keys seemed out of place for a wordprocessor, but then there's that "marg set" key. I'd wondered about some kind of early electronic typesetting system, but I'm hoping someone will know exactly what it is. The five blank keys are weird, too (particularly the out of place black one). The copper ground plane across the top of the PCB is kinda odd as well and not the sort of construction I'd expect from a mere keyboard. cheers Jules

My initial thought is a clone dec terminal printer keyboard.

Mystery mid-70's keyboards
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": http://www.classiccmp.org/acornia/tmp/maxi.jpg 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": http://www.classiccmp.org/acornia/tmp/licon.jpg 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 Jules
