Well. I'm familiar with the early history of CP/M. It's easy to use
one phrase or a quote to enhance an eBay sale. The "quote from
compwisdom web site" is actually a quote from Stan Veit's "PC history"
article from his (memorial) Web site:
http://www.pc- history.org/ pc-software. htm
Veit mashes up the earliest history of PL/M and CP/M in that
description. Based on publications at the time, I know PL/M was first
developed for the 8008, then migrated to the 8080; then pieces of
other Kildall projects plus a PL/M file system "became" CP/M for the 8080.
In my opinion, and I'm reasonably informed and can cite primary
references, I believe that Gary Kildall first developed CP/M between
about 1973 and just into 1975; and first ran it on a floppy drive only
after the fall of 1974 but probably not long after that. That being
the case, he could NOT have FIRST run it on a system like the one on eBay.
