<Wow.... I HAD planned on putting hobbyist 7.2 on my recently acquired <3100/m76, 16Mb, RZ23(wiped). Guess I should set my sights on a bigger driv <or older OS. Hard to believe that this machine came with such a smallish <drive. the RZ23 is a tad small but the 3100/m76 16mb is otherwise fine for 7.2. Try and find a RZ24 or better yet a RZ25(1GB) scsi. The install really wants (full boat) a RZ56 (667mb) for comfort but there is easily 250mb free after your done so you can see it works. If you want to live only with a RZ23 then early V5 such as 5.4 or 5.5 is a good choice if you don't install DECwindows or the optional libraries. I've jammed 5.4 into a RD53(71mb) with 11,000 free blocks when done! Allison
