We ran VMS 5.0 on an 11/730 on the internal R80 for years (it was our VMS 5.x object linking box for deliverables). It fits but is a little cramped. Room for one copy of our product but not lots of room for user files. > RD54's though are a lot less power hungry. RD54s were fine through VMS 5.x. ISTR a buddy of mine put VMS 6.something on an RD54 for me and it was not really large enough. I think he had to remove the help files. For our main 11/750, we ran either 4.5 or 4.7 to the last of its days in 1993 (I forget if we did that last update cycle or not). Our boot volume was 1/2 of a Fujitsu SMD drive that emulated two RM03s, so DRA0 was 67MB. We might have shoved some system stuff on DRA1. I'd have to check the SPD for VMS 6.x but it wouldn't surprise me if 200MB was the smallest supported system device. -ethan
