I have run 2.9BSD on an 11/24 w/3MB of memory and two RL02s. It was not
an easy fit (I didn't have enough room to load the sources and rebuild
the kernel).
I wanted to try to put 2.9BSD on an RK07 or two, but I lost them when my
employer closed years ago (no room to take them with me on top of the
four truckloads of VAXen and PDP-11 equipment I _did_ rescue, including
an 11/750, an 8200, another 11/24, 2 x 11/34, 2 x 11/04...)
At least with 2.11BSD, you can use an MSCP controller without having to
resort to patching/retrofitting a driver (I think there is a way to use
MSCP w/2.9BSD, but I've never attempted it). There are lots of options
for MSCP disks on a Unibus -11, probably the least expensive to aquire
is a UDA-50 and an RA81. There are plenty of things cheaper to ship,
however.
For context, we were using a UDA-50 and RA81 on that same 11/750 in 1984
($26,000 for the drive, IIRC). If you want something older for your 11/45,
you may have to dig harder.
Lots of people who shied away from DEC operating systems were attracted to
third-party disks. You might hunt down something in an SMD or ESDI
subsystem. When we got our first 11/750, we put a Fuji 160MB drive and
an Eagle on it, via a MASSBUS interface to a Systems Industries SI9900
box. I wasn't around when it was bought, but ISTR it was more than 30%
cheaper than DEC disk, meg for meg (sturdy, too... survived several moves
and daily production use for ~10 years).
