I recently bought some 2nd hand devices and would like help in obtaining
information to use them.

Any information: pinouts, supply connections, suppliers name/ address would be
of great value

'Preview streama' modem
Cased in small aluminium box, power, Tx, Rx LEDs on front, 15 way D connector
and 8 pin DIN connectors on rear, BT phone socket inside.

'Paradyne MPX 9600' some kind of communications device.
4 x 25 way D connectors and 4 screw connectors for Tx, Rx lines.

'Uniwell Mplex-8'  RS232 sharer?
master + 8 x 25 way D connectors, baud rate / mode rotary presets and a
single 7 segment LED display.

NCR printer, no visible identifying code 1982+ design, has 25 way D connector
for input (same gender as PC parallel port).

Once again, any help would be appreciated.
