Hello.

I think there might be a problem in attaching 3350s to a 3090, even if you could find any.  The place I was working when the 3350s were phased out did so because the new machine was not capable of supporting them for some reason.  I don't remember exactly why this was, but they also had to get rid of the MSS at the same time because it was tied to the 3350s for staging space (a pity really because it was quite amusing watching it work).

Given access to this particular machine, I think my temptation would be to conserve a working copy of VM/HPO rather than try to get VM/370 to go on it.  Of course, there's always the option of running VM/370 under HPO.
