DEC Professional: software and docs for CP/M and PC-Bridge boards

[Bjoren Davis]

I have two oddball CTI boards for my DEC Professional: a DEC-made CP/M 
board (P/N 54-15641) and a board labelled "VIRTUAL MICROSYSTEMS PRO BD. 
REV 1" which appears to be an x86 MS-DOS board (it contains an 8086, a 
video controller and a bunch of RAM).

I've managed to get them both functional, I believe, but I don't have 
software or documentation for either.

I did find the RCS/RI diskettes at 
https://web.archive.org/web/20040113090630/http://starfish.rcsri.org/rcs/pdp-11/Professional/Pro-CPM/, 
but although the image files are uncorrupted it appears the diskettes 
were not read reliably in the first place.

And I also know that at some point the PC-Bridge software and doc set 
was available on eBay 
(https://www.worthpoint.com/worthopedia/virtual-microsystems-pc-bridge-2-2005998357).

Does anyone know where I can get a copy of the diskettes and/or 
documentation?

Thanks.
