Kilobaud is probably a good guess. I do remember that the kit I saw had a table in PROM that looked up a "tilt" and "rotation" for the Selectric Ball. It was clunky, but a bit more elegant than "104 solenoids". -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org]On Behalf Of Fred Cisin Sent: Tuesday, March 21, 2006 4:43 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: RE: Where have all the Selectrics gone?

Fairly complex, and required tinkering to keep it running. There were also a number of units that consisted of boxes full of solenoids that sat on top of the keyboard, such as KGS80 and Rochester Dynatyper. At the West Coast Computer Faire, around about the 5th or 6th one, there was an outfit demo'ing a unit with lots of pulleys and fishing line, that was printing on a MANUAL typewriter.
