<sigh>

CP/M Plus offered this through the RSX Manager.

Due to all the cool RSX utilities available from Jim
Lopushinsky back in '84, I was able to make CP/M 2.2
and Molecular's N*Star MP/M-II-ish OS a lot more useable.

I mistakenly told Allison that I thought I wrote this stuff!
I just plain got it confused with what I did write...

Anyway, write me privately, I don't want to post the ftp
url in a place that will be harvested someday...
