I think Amdahl also had UTX as a follow on to UTS.
And there was ASPEN (code name?) that was an "MVS" like O/S that
Amdahl had.
In the "DOS" line was DOS/MVT. Not sure if it is still in existence.
For those interested: OBS/WYLBUR became ACS/WYLBUR. It had
support for JES2 up to OS/390 1.3 (I kept that up) and after that
I don't know what happened (I overhauled the JES2 SRB support
with MVS/SP5 to make it easier for customers).
I also had to fix the SSI support for JES2 and JES3 -- don't
remember what the issue was anymore.
SuperWYLBUR (spelling?) was a variant. Do not know what became of it.
BTW - WYLBUR predated TSO and provided services for multiple
users out of a single address space, circa 1967 if I remember the
dates correctly in the source that I used to work with.
