Title: Interesting Tandem Computers Keyboard
Post by: OldIsNew on Fri, 30 June 2017, 20:49:13

At least I think it's kind of cool! Picked it up mainly just based on looks. Is any one familiar with this board? Sold as a Tandem Computers 6530 Keyboard but no label on this one. It's heavy with a solid metal back case. The thing weighs a ton - 9 lbs!

[attach=1]       [attach=2]


Looks like foam and foil:                                                                                        By whom else:     

[attach=3]                                                  [attach=4]



Front plate, PCB back and connector:


[attach=5]                  [attach=6]           [attach=7]


Removed PCB:

  [attach=8]     [attach=9]     [attach=10]



The keys do have a nice feel actually. Looks like a long shot getting it working though - does anyone happen to know anything about the protocol and connector pinout for these boards? Sure would be nice if I lucked out and an existing converter would work!

Yeah, that's key tronic's older version of their foam and foil switches.
