So Mr. Allen didn't want a 7090? That seems rather picky, as they're
quite similar machines, other than that the 7090 didn't have the extra
index registers.
"Soldered with silver and gold"? All of them I've seen use normal
tin-lead solder. I thought silver solder was mostly used for jewelery,
plumbing, and high-temperature stuff, which wouldn't usually be found in
computers. I've never heard of gold solder used for anything other than
jewelery, and wouldn't think it would be useful for computers.
Hmmm... a web search does reveal that gold solder is sometimes used for
soldering gold metalized alumina ceramic plages to gold plated Kovar
alloy assemblies. I haven't seen that kind of thing in really old
computers, though.
