[Coco] OT: Model III/V k/d Schematic

[Brian Blake]

Nevermind, I found the problem. Operator error. As in the soldering iron operator. Me. I soldered in an extra jumper that should not have been there (yeah, I was tired when I was working on this...). Once I figured that out and removed the jumper, all is well. All keys work as they should. 
   
  Now, I need to get a good copy of LDOS and a manual... off to the internet I go....

There is a small piece missing from the one I have where the center support went thru the back keyboard ass'y at keys 37 & 38 (or 'L' & +;'). I have jumpered the k/b to where all of the keys work, however, there are a couple of problems: hitting the j or l key types both j&l at the same time, b & d does the same thing.

This is an improvement considering that over half of the keyboard didn't work when I started. But I need either a schematic or a picture of the area that has the hole in to see where exactly I screwed up...


Thanks,
