Hi!
Surfing the web, I have found an old (German) announcement of
DR Multiuser DOS 5.1 from 1992. In this announcement they spoke
of the real-time operating system DR FlexOS and a graphically
environment named DR X/GEM v2.0 with support for 16- and 32-bit
applications with 4GB address space, which was under development
at that time. I thought this might be interesting to some of you...
Since the real-time operating system IMS REAL/32 7.50+ derived from
IMS Multiuser DOS 7.xx which derived from DR Multiuser DOS 5.1, I was
wondering, if FlexOS and REAL/32 could be somewaht compared in this
respect. Although they spoke of version 2.0, this is the first time,
that I saw the product name 'X/GEM' at all (and GEM 3.1 was in 1989).
Further, I was interested if Caldera also owns the sources of FlexOS
and X/GEM (AFAIK, they did not mention them in their announcements).
Anybody having additional information?
Bye,
Matthias
Errata:
Since I'm trying to clear the confusion concerning the former
DRI operating systems and their facilities (including their
successors), not to introduce new rumours, I have to correct myself:
When I spoke of the REAL/32 API some days ago, it was Concurrent
Control's CCI Multiuser DOS 7.22 Gold, where Novell holds some
copyrights up to 1996 (apparently in the NetWare area), but it
was IMS REAL/32 with it's IMSCDEX.EXE driver, that definitively
is a derivation of the NWCDEX.EXE 1.00 driver from Novell DOS 7 betas.
