Modern TVs don't have a composite input. :)
- rbanffy 5y agoIt's a shame they didn't have SCART output.
- LeoPanthera 5y agoI don't think that's actually true. Even my shiny new Sony 4K HDR TV, bought literally this year, has a single composite input. It's certainly being phased out, but it's not gone yet.
- beagle3 5y agoMy new Phillips 4K OLED does not, which I only discovered when I wanted to connect my https://en.wikipedia.org/wiki/C64_Direct-to-TV https://en.wikipedia.org/wiki/C64_Direct-to-TV to it.
- Jaruzel 5y agoTo explain further: The internal composite signal of the ZX81 (before it hits the RF modulator) has a poor "back porch"[1] signal, which prevents a lot of digital TVs from showing a steady image of the ZX81s screen. The composite mod for the ZX81 rectifies this, so the composite output can be feed into either a modern TV that still has a composite input, or an inexpensive composite-to-HDMI converter. --- [1] https://en.wikipedia.org/wiki/Horizontal_blanking_interval https://en.wikipedia.org/wiki/Horizontal_blanking_interval
