In the computer center, beside the 7094/7044 Direct Couple, Caltech had a Datatron/Burroughs 220. It had a tape drive for metallic tape. If it detected an error, it backspaced and punched a hole in the tape. By 1964, the 220 had only two jobs: One was to read paper tape from the synchrotron into the 7044. The other was to print on its "whippet" printer, a very fast electrostatic printer that put soot onto a thermal paper that was then heated to "fix" it. There was a huge variac under the printer to adjust the heater. The perfect setting was between two windings. Too cold and the soot fell off. Too hot and it was melted and smeared into an almost illegible mess. But it was very fast -- and only 80 columns wide. It was about the size of a KSR-33.
