I was wondering how well a Greaseweasel would write

I've not tried this with my kyroflux, so no comment.
Also, I saw that someone had images for Venix-86
Rainbow and I was
wondering if they would be interested in sharing them.
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.

floppies in RX50 format no problem.
The RX33 was a pretty standard PC floppy drive AFAIK, just configured
(with
jumpers) to work as an RX33. You may find better milage configuring
it as a PC floppy drive, as PUTR expects to work on PC drives at the device
level. Having a real RX33 might be throwing it off. Don?t take it as
gospel, since i?ve not got an RX33 to test it with.
Not sure if PUTR can copy images to a floppy, as i?ve only used it to
build a
bootable RT11 disk, and make a few RT11 disks out of the contents
of images mounted by PUTR. You might find it better to work on a blank
formatted floppy and build up from there.
I have a utility to go between real floppies and images, it's included
with my RSTSFLX utility. It can deal with interleaving, so (for example)
you can have an image file in logical block order as they usually are, and
copy that to a floppy in the correct physical order. Or you can have an
image that's in physical order, as you would use for the xHomer fork of
SIMH.
Look for svn://akdesign.dyndns.org/flx/trunk -- the program I mentioned
is rx50.py.
I have no idea if this can be made to work on Windows, but it runs fine on
Linux. (I did once, long ago, write code for DOS -- DJGPP -- to access the
PC floppy in the right way to read/write RX50 format floppies, but while
that works fine under Win95 it probably won't work under WinNT derivatives.)
