    • It should be no problem at all, since the ZX-HD just probes if there are video memory changes, which is independent of the ROM inside the ZX Spectrum.
      So the ULAplus commands in the SE BASIC ROM should work fine!

  1. This is labelled as working with the DivMMC Enjoy mini. Does it have a through connector or will a splitter rinbbon be needed

    • Yes, the ZX-HD indeed has a throughput edge connector, sorry that was not clear!
      I’ve just updated the description of the ZX-HD with that info.

      So the DivMMC EnJOY! *mini* can be connected easily.


  2. Hello.
    No doubt a dumb question but what is a Raspberry PI?
    Can I just purchase this kit to play my ZX Spectrum on my Panasonic HD TV, or do I need this Raspberry PI product?

    • The Raspberry Pi (model ‘Zero’ in this case), is a small board computer, which can operate standalone with a Linux distribution, or can be used to control hardware.
      We have chose to use it with the ZX-HD, since the Raspberry Pi Zero carries a HDMI connector, for which license fees have been paid already.
      The Raspberry Pi ‘listens’ to changes in video memory on the ZX Spectrum, and builds up its own HDMI buffer.

      So the ZX-HD will only function with Raspberry Pi Zero, but I offer a kit without it since some people can obtain a Raspberry Pi Zero themselves cheaper.

  3. The difference in picture quality is astounding. Colors pop, visuals are razor-sharp, and the overall clarity is unmatched.
    In short, if you adore ZX Spectrum, ZX-HD is a must-have. It’s not just a product; it’s a testament to preserving gaming history.

    Thank you, Ben, for this outstanding innovation.
