Had some bad luck with one of the upper row arrow keys on my 128. The plunger decided to explode and the spring is MIA. Wondered if anyone had a spare they would be willing to sell me or had any other ideas of where to source one? Looking on eBay they have a ton for the 64 but nothing for the 128. I'd love to get this keyboard put back together and refuse to rebuild it just to tear it apart again when I find the parts. Probably important to mention that I'm based in the US seeing as paying international shipping for such a small item would break the bank. Thanks!
