Since my beloved HP-34C is acting flaky, even with new batteries, I'm thinking I have the dreaded non-soldered version. It was made in 1980, and I guess the run went to 1983, so where is the cutoff for the soldered versions?
Every time I see a Spice for sale on Ebay, they all seem to come from 1980 or earlier, at least in my short time of looking. Is it that they didn't produce as many of them after that year, or just that people primarily sell the flaky ones. I'd love to get my hands on a 34C without this problem.
I guess I'll give the pin cleaning a try first.
