David Given, in 2019, coded a vi clone from scratch in a day – and it’s a very good clone!
So, while working out some frustrating memory corruption bugs in FoaK D. wanted some “fun code” and ported the same editor, QE, to NextZXOS instead of its original CP/M clone, CPMISH.
You can find the resultant (discretely contained) port of the software on our GitHub, or part of NextZXOS.
