Subject: Re: What PDP11 OS in 20MB Disk Space
Straight 11M (non-plus) does. (fits in 10 actually) Early RSTS/E, like
v8,
should, but not 10 and likely not 9. RT11 does.
BitSavers looks like it has 11M 4.0 in a 19MB virtual tape, here:
http://bitsavers.informatik.uni-stuttgart.de/bits/DEC/pdp11/magtapes/rsx11m/
Assuming that is the right one to go for?
I know next to nothing about RSX, what is the difference between plus and
non-plus?
