The 134.5 >was used in a six bit commodities ticker,... 134.5 was also the baud rate used by the (half-duplex) IBM 2740 and 2741 Selectric typewriters. This works out to 14.9+ characters per second, since they used a 9-bit code (1 start, 1 stop, 7 data - sent HIGH BIT first). 1050 was what.. anybody.. I seem to remember Kleinschmidt reperforators (tape punches) running at that speed. Marc Kaufman (kaufman@Neon.stanford.edu)
