Who remembers the Jupiter Ace? https://en.wikipedia.org/wiki/Jupiter_Ace

I still have one - or most of one - that a friend of the family gave me after he bought it and couldn't figure it out and bought a ZX Spectrum instead. Sadly the vacuum-formed plastic case went all crumbly.

I'd love to build a homebrew one.

Sadly you've missed a recent opportunity with the Minstrel Forth https://www.thefuturewas8bit.com/shop/tynemouth-products/min... a modern clone of the original. There is a bit of cheating by having a micro controller do the video timing along with a dual port RAM for the video, but I'm happy enough with that.

Alternatively you could go with Grant Searles schematic http://www.jupiter-ace.co.uk/hardware_diy_ace.html

I have a circuit diagram and Kicad, and it wouldn't cost much to get a board made.

Chap in this video has Jupiter Ace emulated and running upon a Raspberry PICO, even handles display driver for VGA output. https://www.youtube.com/watch?v=XhDkOIs2Au8

I had one - it was the first computer I owned. It was cheaper than a ZX81.

Sadly, I missed the ace when it was released as hardware, but whiled away many hours with the xAce emulator. I was able to find most of the docs online as PDFs, and they were really pretty good.

I do, it was a regular ad on Speccy magazines.
