The building was one of the tallest around at that time. Its walls were all glass. The computer had 20 or 30 tape drives and was to be used for a new system that would run a transaction system during the day and a batch system at night. The output from the daytime online system would feed the nighttime batch system for master file updating. Some of the master file runs would take hours. Most of the testing was done during the daytime. On the first day of production there were the usual problems and the batch system was running behind schedule. At dawn when the sun came up it shined through the windows on the tape drives which immediately went into high speed rewind and unloaded the tapes. The sun had shined on the end-of-tape sensors which caused the tapes to rewind. After that one of the nightly duties of the graveyard shift supervisor was to insure that the drapes were closed before the sun came up. -- Dave Turner 415/542-1299 {att,bellcore,sun,ames,pyramid}!pacbell!dmt
