FInally able to reply on here . . ..
I have a disk with the software. Sparse documentation and apparently source code, tho I can't read it -- don't know if disk is failing or my drive is.
I doubt that I'll ever use this, so if you want it, send me an SASE (wb4gcs address is good at QRZ), and I'll send it.
NOTE: It is (apparently) not a factory disk; I don't know it's origin. I know that I won't use it, so happy to give it a good home.
Also, I did run across a source for a manual.
