Yeah, the Voyager used three RCA 1802s (the CPU used in the Elf, SuperElf, COSMAC computers), because they used a SOS process (Semiconductor On Sapphire) which was extremely resistant to electromagnetics, radiation, etc. I think about that every time I see the silly original Star Trek: The Motion Picture (for those who haven't seen this masterpiece, the RCA 1802-powered Voyager runs into an alien civilization who accelerates it to about the level of HAL with a learning disorder, then gives it a big EMP gun and points it back towards Earth - gee, thanks) Kai -----Original Message----- From: Max Eskin [mailto:max82@surfree.com] Sent: Saturday, July 03, 1999 2:25 PM To: Discussion re-collecting of classic computers Subject: Re: E-bay stupidity! was Re: height of folly On Sat, 3 Jul 1999 jpero(a)cgocable.net wrote: So, where _did_ the story about the Voyager using a 4004 come from? I've seen it in a variety of places, and never questioned it. As it happens, I think that this is a fairly valuable item, though perhaps not worth $600. Although it's not the _first_ microprocessor (as we learned a year ago), it's definitely the first commercial one. --Max Eskin (max82(a)surfree.com) http://scivault.hypermart.net: Ignorance is Impotence - Knowledge is Power
