Start really enjoying your TS1000/ZX81 on a modern TV!

There are other adaptors, but this Composite Video Adaptor for the TS1000/ZX81 gives the best results - just check the Timex/Sinclair forums and online product reviews. The results are a joy to behold - the resulting video display is crystal clear.

You can enjoy using your TS1000/ZX81 on modern televisions too.

I have created clear installation instructions for the TS1000s and U. S. ZX81s with Channel 2-3 VHF modulators, (as well as the European ZX81s that have channel 33 UHF modulators).

You can install the ZX8-CCB in the TS1000/ZX81's RF modulator, or you can install the board elsewhere in the the computer without disturbing the RF Modulator and connect it to an external RCA video jack. Because it is not unheard of for the keyboard's flexible cable to become brittle with age and crack if stressed, this second is the more cautious approach because it does not require you to remove the TS1000 circuit board from the top of the TS1000 case and disturb the membrane keyboard.

NOTE: While it is not particularly difficult to install this adaptor, I would only recommend you purchase it if you have good eyesight and are experienced soldering electronic components. I only want happy customers. It is not the case that "anyone can do it".
