  16. Went to the newsagency for Retro Gamer as My Zevious Seven gets a mention in the August issue. That copy wasn't in stock yet, but to my surprise, there's a good #ZX81 write-up in the May 2026 issue with a ton on old and new 81 games and yay, Tut-Tut and Minos Knossos get a good write-up!

  31. Forgot to add the finished assembled shot...
    PCB rebuild project successful.
    Unregulated so actually showing 12v with no load. 🤣
    I'll actually use a modern switched 9v for my ZX, but I wanted to get the original supply back working again.

  36. Next step replace the ancient 7405 voltage regulator with a modern decent one.
    But I'm on the fence whether to do anything else to this. I think I'd prefer to keep it pristine(ish).
    It feels like these initial mods are in keeping/acceptable to the age of the zx:
    * connecting to an analogue TV is impractical now, so a composite upgrade feels ok
    * the keyboard membrane was toast (cracked and disintegrating) - the replacement looks identical
    * and the power regulator can be updated on the same footprint to solve the power/heat issues.
    I *could* upgrade the internal ram to remove the need for the external ram cartridge and fit a modern FPGA ULA to fix the video quality and add features like 32k support and high res graphics..... but that feels wrong somehow wrong and too much. 🤔
