Which video mod for composite?

[Dukes909]

Shielded or braided screened co-ax cables are available with RCA / phono connectors. Although it’s not possible to tell on most pre-made cables with moulded connectors.

Look for cables specifically described as high quality video cables.

Will do, thanks

The 210E version of the ZX81 ULA is pretty compliant with the standards.

It’s better, but I would not describe it as pretty compliant.

Well, as far as I know it seems to be compliant with a standard black and white signal. If there are major deviations that you are aware of please elaborate. My TS1000 with a version 210E ULA has displayed a decent picture so far on every TV I have tried it on, including my modern flat panel oLED TV.

I’ve made my own composite circuit, based on a transistor, a capacitor, 2 resistors and 2 diodes. Works perfectly on my Timex Sinclair 1000.

Would you share the schematic? What kind of monitor are you connecting the 1000 to (which seems to me has as much to do with the quality of the resulting display as the circuit)?
