Gold edge connectors are bad, haven’t you heard?
Just kidding, but there’s been a small discussion on the Facebook group where it’s being claimed
tin-plated is better and won’t wear out your CoCo’s cart port connector as quickly as gold. And that
that is why Tandy didn’t use it most of the time, not because of cost.
Personally I don’t buy it, I think gold plated edge connectors are the way to go, even though they
cost a bit more. You can certainly argue it’s not necessary, but worse? lol.
