Teletype Model 28

The Teletype Model 28 is a product line of <a href="/facts/Teleprinter/pn5SQKTf">teleprinters</a>, typing and non-typing tape perforator and tape reperforators, fixed head single contact and pivoted head multi-contact transmitter-distributors, and receiving selector equipment. Regarded as the most rugged machines <a href="/facts/Teletype_Corporation/dcsgSl36">Teletype Corporation</a> built, this line of teleprinters used an exchangeable type box for printing and sequential selector "Stunt Box" to mechanically initiate non-printing functions within the typing unit of the teleprinter, electrically control functions within the teleprinter and electrically control external equipment.
The Teletype Model 28 is more rugged and more expensive than later Teletype Model 32 machines. The Teletype Corporation introduced the Model 28 as a commercial product in 1953 after being originally designed for the United States military.

<li>the Model 28 KSR (Keyboard Send and Receive), which lacks the paper tape reader and punch;</li>
<li>the Model 28 RO (Receive Only) which has neither a keyboard nor a paper tape reader/punch.</li></ul>
