Talk:Systems Engineering Laboratories

When we look at history and record "SEL's first computers, such as the 810A, the 8500, and the 8600...", where is the 840A and the 840MP? I spent many hours on the factory floor (Plant 2 on Federal Highway) checking them out as they were assembled.

Ah, the good old days...

The SEL 840 was used in the Lockheed C-5A Simulators where there was 1 at Dover, 2 at Altus and 2 at Travis Air Force Bases. Originally made by Curtis-Wright, maintenance and updating was taken over by Lockheed-Georgia Co. in Marietta, GA during the 1970's. — Preceding unsigned comment added by 209.179.95.95 (talk) 00:27, 31 March 2015 (UTC)[reply]

Twin SEL computers with large disk subsystems were installed in bldg 23 at Goddard Space Flight Center in the early 1980s to develop the first Hubble Space Telescope Data Capture Facility. The SELs were selected because of their high bandwidth I/O busses to support the high volume and high rate HST data to be received from the NASA ground network. Two identical systems were installed so that one could be a hot backup for the other. Twin Custom VME-bus front end channels were developed to capture and initially unwrap the telemetry data from transport protocol levels at the high rates necessary to feed the SEL. Design documents should be available from NASA archives. --Wherbert (talk) 00:32, 26 June 2016 (UTC) — Preceding unsigned comment added by Wherbert (talk • contribs) 10:33, 28 April 2015 (UTC)[reply]
