Hey guys, picked up a box of older 80's calculators today. I checked ebay and they don't seem to be worth anything so I pulled them apart to get some low grade boards. That's where I ran into a couple things I wasn't sure about. All of them have a glass display that has pins coming out the bottom that are soldered to the board. Should I leave these in place or cut them off? If so should I keep or trash them? Also all of the "Royal" adding machines have a small board 3"x2" that seems to have gold plating for connectors but no resistors or chips. What pile should I put these into?



Sorry I haven't been here long enough to post pictures so hopefully you guys might now what I am talking about.

Thanks,
Mike
