Picking up some teletypes


I picked up a Teletype model ASR 33 today and brought it home. It is in pretty clean shape, but will need restoration to get it working properly. There is also a front panel and knob missing.

On eBay I saw a model 15 for sale, actually the military TG-7-B model which is mainly different because it fits into shipping crates for transportation in the field. It had a low starting price and no apparent interest from others, so I placed a bid and won it for $99. I do have to drive down to southern California to pick it up, but it is a great deal even with that.

Finally, I was given a model 15 Transmitter/Distributor (TD) which is a unit that reads paper tape and transmits it as serial data. This will allow me to use paper tape to drive the printer.
