[GreenKeys] "Teletype" Equipment Cabinet For Sale in Ringgold, GA

[Jim Haynes]

Cabinets like that were used for several Teletype large systems.  They are
relay rack size, but a little wider than the usual relay rack cabinets.

SECO - a weather data collection system for the CAA, where the cabinet
held a couple of SOTUS sequential selectors and other stuff used in
collecting the hourly weather observations from airports.

AN/FGC-5  - four channel time division multiplex using vacuum and gas
electron tubes.  One cabinet for the transmitting terminal and another
for the receiving terminal.  Later transistorized multiplex systems,
AN/UGC-3 and AN/UGA-1 used standard military rack cabinets.

ADIS - weather data collection and dissemination system that replaced
SECO.  A switching center used a dozen or more of these cabinets.  Some
held two reperforator-transmitter stands in the bottom and shoebox size
electronics modules in the top.

BDIS - another communication switching system for FAA that handled
flight plan and administrative messages.
