So Jack how long did it it take to make the calculations back then.  Now what is it a split second computer driven calculation.

Heck, that was so long ago that they let Kepler do them! 😆

The Univac (I think either 640 or 1218 don't remember)  computers had a "4 microsecond memory cycle time".   The telemetry processors, which fed data to the Univac's had a 4096 core memory and a slower memory speed.  In 1966 speed wasn't a pressing consideration.  The Univac's were connected to the 4800 BPS "High speed" trunk lines to transfer data to Houston control center and to Goddard Space Flight Center.   Most of the data, tracking and telemetry was written to mag tape and the tapes sent to Houston.   Both the Univac and the Telemetry processors were discrete component (transistors) machines.  The I/O console on the Univac was a Teletype machine.

Thanks Jack for the write up.  Must of been a stressful situation but exciting at the same time.
