Anderson Jacobson ADC212

Another device that had already fallen out of use by the time I started. Manufactured back in the days before grey or biege plastic was the norm, this little box is actually made of wood.

Opening the front half reveals the couplers for the handset plus switches for half or full (duplex, I presume) and the power switch.

As well as looking its age, it’s also showing its age as well. The black foam in the lid has gone hard and drops dust onto the coupler housing everytime the lid is closed. The foam around the couplers themselves is also going the same way, sadly, and the rubber of the couplers is also going hard:-(

Opening the back reveals the glorious components that formed the circuitry.

On the side are TTY connections for a terminal, a D-25 serial connector, labelled CCITT, plus a very proprietry mains cable.

I have no idea on the speed that this thing used to communicate at, nor do I know what systems is was used for. I doubt it was much fun tho’!
