Description

There are two main problems which face users of Sinclair ZX81 Home Computers -

a) how to get a picture on a modern LCD television without manual tuning, and

b) how to get a good display on a colour television.

(a) is caused by the weakness of the video signal from the Sinclair ZX81 and can be cured by converting the ZX81 to composite video.

(b) is more difficult - early ULAs result in a black cursor and text against a very dark grey screen, making it impossible to view the ZX81 screen.  If you can find one of the later ULAs (about as rare as hen's teeth), then this would cure the issue.

We have therefore developed the ZXVid.

The ZXVid is a board which replaces the insides of the UM1233 UHF modulator on the ZX81 and provides excellent composite video output for modern televisions, and also incorporates the back-porch latch required for early ULAs which produce a very dark screen on modern colour televisions.

This provides a nice neat solution, and if you require, you can even make up a SCART lead to plug into the unit.

This is the fitted version of the ZXVid - you will need to send your working Sinclair ZX81 unit (not the power supply or leads) to us and we will fit the ZXVid unit, test the ZX81 and return it to you using tracked postage.

This is the simplest way to upgrade your ZX81 output!

We also offer two other options:

  1. The ZXVid unit built into a UM1233 UHF modulator - you then need to de-solder the existing modulator on your board (soldered in two places), remove the same two wires, and solder the new modulator containing the ZXVid
  2. A self-fit version where we just supply the unit plus wiring - you need to remove the innards from your TV modulator and solder the new components)

See our other auctions for the alternative options.

Questions and Answers

  • Question: Can the ZXVid be fitted or used with the TS1000?

    Posted by b***a (2) - 11/06/2015 21:44:27

    Answer: Yes, these work fine with the TS1000 and TS1500 - although for the TS1500 you need a longer wire. As you are in the USA, you would be better purchasing the self-fit version unless you want to send you TS1000 to the UK for fitting - see http://www.sellmyretro.com/offer/details/2338
