I've not tried this with my kyroflux, so no comment.

https://fosdem.org/2022/schedule/event/venix/ for my recent Venix-86 talk
https://github.com/bsdimp/venix/ has all the images you'll need, but maybe
not in the most useful format, but see dist/rb/README.md with details.
You'll also want to install the Boston Software Works (BSW) version since
it supports most hard drives and not just RD50s.

Please don't hesitate to get in touch if you have any questions.  I've been
running it on and off for a while now and would love to see more use it.

Also, you can run this with mame, though I've only done it with the Rainbow
100B, none of the other models. You'll need at least 256kB, but happiest
with max (892k) settings.192k might boot, but anything smaller will not
boot.
