If you have a punch and reader you have a ASR

First check witch UCC you have so you can obtain the correct wiring diagram

A good place to download manuals is  navy-radio.com

There is a good chance the unit has been modified before you got it

Good luck

Dear Mr Cembura.

I have aqquired an Teletype model 3321, beleive it should be an ASR.

Now, I have problems finding ut exactly what models and options it haves, since it internally  does not look as the drawings/pictures in the various manuals, I’ve found.

To the left it has the paperpunch and reader, the printing unit is friction feed.

To the right there is a number of PCBs in slots with edge contacts, and i cannot, apart from the power-card, identify these cards.

Molex plugs 2 and 3 are missing with emty slots in the sheet metal console.

It seems that Molex plug 1 is some sort of incoming data and Molex plug 4 is connected to two switches on the cover, the cover has 4 switches, but only 2 are used and functional.

 

Apart from this, the whole cover is smashed in pieces, and has to be repaired, or replaced.

 

Is it possible that you could help me with some information, I would be very happy.

 

The unit is marked with  ”Model 3321 3WF) Where the 3 last lettters is quite unreadable, so it could possibly be someting else.
