Im a dabbling electronic musician, so I understand a lot about keeping very old technology functional in the modern world. A lot of these old synths (all mine are digital synths) are irreplaceable with newer technology. My stuff goes as far back as the mid 80s, but there are people that restore and maintain even older hardware. Recently a synth tech restored a couple of Crumar GDSs. These were CPM based S100 bus computers with audio synthesis cards and a program that let you design sounds using a terminal interface, they play them with a music keyboard. These old synths are very difficult to keep going compared to something like a MiniMoog from the same era, because they are dependant on software, 8" floppies, and operating systems and terminals far out of common usage. Nonetheless this is a pretty amazing machine, and a very cool restoration: http://www.vintagesynth.com/forum/viewtopic.php?f=1&t=77037 http://www.vintagesynth.com/forum/viewtopic.php?f=1&t=77037
