No, it was $1 million!!! To get what's common in today's computers, you'd be spending around a half a billion dollars!

No, never heard of that one. I had my share of tubes, with that Teleregister system. It was built with plug in modules. For example one common module, was a dual flip-flop, which used 2 dual triodes and 2 pentodes. The tubes were mounted on one end of the module, with posts connecting the platfor holding the tube sockets, to another one, with a large connector (similar to an octal plug, but with more pins) at the other. In between, was a circuit board, holding all the other components and connected to the plugs & sockets, with wires. It was real "fun" trying to unplug a module, with your fingers surrounded by hot tubes. ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca
