Well, at least there are two people that have built colour-PET (-compatible) machines, at least me and Steve Gray.
I _think_ there are some more who also built Steve's colour-PET version, and I hope to get more traction on with the Ultimate PET model I am in the process of developing...
But you are right, probably only two confirmed owners. I was just very positively surprised to see your colour version of gridrunner for the colour-PET. I am actually demoing it when possible when I show my system.
Anyway, I totally understand avoiding effort for such a small user base.
Thanks for your reply!

Edit: and VICE _does_ emulate the Colour-PET after all :-)
