Other 8-bit computers that have had modern re-issues:

Commodore 64 -> THEC64 https://retrogames.biz/products/thec64/

Commodore VIC-20 -> THEVIC20 https://retrogames.biz/products/thevic20/

Sinclair ZX Spectrum -> ZX Spectrum Next https://www.specnext.com/about/

I would personally be interested if some of the iconic computers from the 16-bit era were also re-released (Amiga 500, Atari ST). (I am into electronic music and having modern re-creations would make them more viable in a live set-up as you wouldn't be too worried about reliability, which is an issue with vintage machines).

Having said that, for anyone who is feeling nostalgic and doesn't want to spend a ton, a Raspberry PI 400 can emulate all of those and it's close enough in terms of form factor.
