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.

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? |
