Timex Sinclair 2050

[3] A lot of people bought the modem board and made a custom casing.

The device supports all the Timex Sinclair machines,[10] coming with a cassette containing modem control software for T/S 1000 and T/S 1500 on side A and for T/S 2068 on side B.

[11] It was based on the Intel 8251 USART chip and very slow (300 bit/s).

A magazine published a way to modify the modem to convert it to a serial port, allowing users to connect faster modems.

At least two bulletin board systems based on the T/S 2068 computer and TS2050 modem existed as of 1988.
