Would you believe we just threw our trusty Flexowriter away a few months ago? For the last 20 years it held down a workbench. As I recall, it drew about an amp every time it printed a character. No experiment using electronic equipment could be done within 100 feet of one. The FCC would not approve! Of course the LGP-30 was quite a hunk itself: The LGP-30 is 26" deep, 33" high and 44" long, exclusive of the typewriter shelf. The computer weighs approximately 800 pounds and is mounted on sturdy casters... It had 113 tubes and 1450 diodes in 34 cards (of 12 types). Main memory was a drum with 4096 words. It had 16 op codes, so I guess it was an early RISC machine. Hmmm... not too much to do with UNIX. I doubt anyone ever did a port. I couldn't resist, since I found the manuals for it. -- Robert S.
