Hello David
I saw your posting on the cctalk mailing list regarding RSX180.
It is Hector Peraza that's been tinkering with this. He intends making the
full source-code available via SourceForge or GitHub but is still working
on preliminary web pages and documenting etc. No doubt he will provide you
with more details.
I've been tinkering with a Z280 system designed by Bill Shen (the Z280RC on
the RetroBrew web site at
https://www.retrobrewcomputers.org/doku.php?id=builderpages:plasmo:z280rc )
and have contacted Hector about porting it to the Z280.
A Z180 system is also on my hobbyist "to-do" list. Should you decide to
produce another run I'd be interested in one. Most likely I'd use a
CompactFlash on IDE interface and an GoTek style floppy emulator with it.

That is the easy part, where is the 99 cent dumb terminal to go with it?

While we are talking about the P122....?? :-)
Has anyone tried and/or had luck using an 8" floppy drive
on the P112?

I haven't tried it myself, but a few of my customers have reported success doing so.

The answer is Yes, if you really understand what your asking.
I've not used the P112 but I have used the combo part in it for FDC
interface and it does/can work with 8", 5.25", 3.5"
drive so long as you get the wiring right as they all differ especially
the 8".?? It does do CP/M 8" SSSD format
which was the primary interest (RX01 was secondary and does that too).
The second half of that is the driver for the device as it can do it but
it does have to be programmed.
The combo chip is basically a 765/8272 with 9229 for clock and FDC
interface inside and is not unlike the
37C65/37C765 and remote relations.? Basically it can do any fairly
standard soft sector thing? assuming
its not one of the odd 1771/1773 formats or based on some unique
controller (intel 2D M2FM and RX02).?
The chip used was from the PC world and most people that had issues with
PCs and 8" disks were
trying to work with existing PC FDC drivers limitations.
