In case someone might know.....
I bought a "for parts" PC-1500 Pocket Computer on a lark (mainly hoping the display might be the same as my fully blackened EL-5100 display) and it actually works fine except for the F2 key. I dug in and found one of the red "inspection dots" stuck right over the F2 contact grid. Now the question is: is this a total accident or was this done on purpose for some reason? One other (possibly) odd thing is a handful of "blue wires" on the main PCB which could be factory fixes but again, hard to tell. At some point I may go for the display swap but for the moment I thought it might be fun to play with the 1500 for a while. I may just remove the dot and see what happens but I thought I would ask for thoughts first.
Wisdom welcomed!
