Tandy used tin plating on the TRS-80 Model 1 expansion connector, it was
rather unreliable and some people soldered gold-plated connectors onto their
units. I never bothered and just unplugged and replaced the connector each
time I used the computer, or kept the power on all the time. The current
through the connector kept it conducting properly.
