I buy the same edge card connectors that MITS
bought, minus one part number
digit because I am buying non gold plated pins. The contacts are gold
plated. If I buy 10 from DigiKey they are $14-$15. If I buy direct from
the company they are $17-$20. : )
I learned that the rule was "gold against gold" and "tin against tin"
for edge connectors and IC sockets. Otherwise, there would be
galvanic corrosion between the tinned and gold surfaces, particularly
in high-humidity environments.
Is this not true?
