The Teletype Corporation produced the Model 40 and 4540 electronic display terminals
and chain-based printers, also called the "Black Line." There was an optional Magnetic
Tape Terminal (Model ?) as an adjunct for the Model 40 equipment.
(need more poop here)....
Standard Models: 40-KD, 40-ROP, 40-KDP
|The M40-KD is the Keyboard-Display unit, and the M40-ROP is the Receive-Only Printer. Above, is an M40 system at NADCOMM.|
|It's a big fella. This one has several mag tape units, but is missing the keyboard. The CRT has a wide aspect ratio (132 col?).|
|This printer uses wide (132 col?) sprocket-feed paper? This one has buttons on the front for ?|
|Inside, you can see the chain that moved the printhead across the paper.|
|This one looks narrower, for standard paper ?? It does not have the buttons on the front.|
|The magnetic tape units could store xxx on a cassette tape ???|
|Does this "Data Terminal" serial plate belong on this mag unit?|
