Timex Sinclair 2050
The Timex Sinclair 2050 (TS2050) was a modem made by Westridge Communications for Timex Sinclair, a joint venture between Sinclair Research and Timex Corporation. It started out with Timex Sinclair branding and a Timex case, then was renamed Westridge 2050 when Timex left the computer business as the modem began production. Many people bought the modem board and built their own cases.
The TS2050 works with all Timex Sinclair computers and came with a cassette that had modem software: side A was for the TS 1000 and TS 1500, and side B was for the TS 2068.
It used the Intel 8251 USART chip and was quite slow, running at about 300 bits per second. A magazine described a modification to turn the modem into a serial port, which allowed connections to faster modems.
By 1988, at least two bulletin board systems (BBS) were running on the TS2068 computer and the TS2050 modem.
