The TS 1500 uses your standard television for its display, "broadcasting" on either channel 2 or 3. It defaults to TV channel 2, but if you press the "3" on the keyboard within a few seconds of turning the computer on, it will then use channel 3 instead. Very tricky indeed!

This improved keyboard on the TS 1500 has the same layout as the earlier versions, meaning that each key may do up to five different functions, depending on how many keys are pressed and in what order.

Although the TS 1500 comes with 16K internal RAM, an external 16K RAM pack can be added for a total 32K RAM. A few keyboard commands (POKEs) are required for the system to recognize the additional memory space.

Being a very inexpensive computer system, an equally inexpensive data storage method makes the most sense. This was accomplished by utilizing a standard cassette recorder for data storage and retrieval. While almost any consumer recorder would work, Timex sold the very shiny Timex Sinclair 2020 recorder for that professional touch. From

I always wanted one ! My dream as a builder was to make a better 1000 using a Hitachi CPU which has included the z80 instruction set. Still got the parts. Once I built a 256K Memory with 256 22 Pin chips with Wire Wrap ... Ouch ! ... Used Power !

I bought one of these at a close out sale, payed around $39.00 plus shipping. It had a better keyboard and the built in 16k helped out a lot. A much improved version of the TS-1000. I still have one of the Tmex-1500 computers and it still works. Too bad Timex didn't stay in the computer business for very long. Had some really great learning computers for it's time.
