For anyone just discovering this (I'm posting this after someone re-posted Dave's review a few places on Reddit etc today), there were some further developments:

- sadly, Marcel van Kervinck (posting as marcelk here) died in May 2020.

- they stopped selling kits in mid 2020, not long before I discovered the project during lockdown and would have bought one. Over 1000 were sold.

- in addition to the custom interpreted vCPU 16 bit instruction set they made up, and which the menu system and games were written in, a ROM was later developed that instead implemented the 6502 ISA at about 1/8th the speed of a real 6502, making the board able to run Apple I programs including WozMon.
