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.

Mystery mid-70's keyboards

2019-12-28 Thread Jules Richardson via cctalk



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
