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
