Here are the disk images. The “V” disk has the IOBYTE set to use a VDB-80 as the console. That’s what was hanging me up… I created an “R” version for RS-232. The CP/M disk I got is an “R” version.

Unfortunately, SD Systems didn’t distribute their software on write-protected media, so I have no idea if this is original or has been modified.

These need the SD Monitor at E000 and DDBIOS at F000. I am still working on getting original copies of those.
