Having met with storming success (thanks Warren) in getting UNIX v6
and v7 up and running on my 11/34, and having recently (well
yesterday) acquired an 11/23+, I'd like to put UNIX on the latter.
Now, the 11/23 has 128Kw, a 10Mb RD51 winchester and an RX50 floppy. I
need to get hold of a version of UNIX (pref. v7) The UNIX in question
obviously needs to support the RD51.
In the case of the 11/34 I built a UNIX image under a PDP-11 emulator
and KERMITed it to the 11/34. I plan to do the same in this case ...
Any suggestions welcome. Does v7 support RD series drives? If not,
what does?
Cheers,
Bob.

v7 doesn't support RDs (just looked thru the archive), and I don't know
of anything that does. You'd probably have to write your own device driver :-(

Hi -

In article by Bob Manners:
Warren's correct. MSCP support did not enter the 'BSD' picture until
late 2.9BSD or early 2.10BSD. TMSCP support for tapes didn't come
about until early 2.11BSD when I "borrowed" the driver from 4.3BSD
(who had earlier borrowed it from Ultrix).
It should be noted that the MSCP (and to a greater degree TMSCP)
is a *pig* - it's the largest driver in the system, rivaling the
TTY subsystem sizewise.
An 11/23 is already extremely cramped for address space even using
simpler/smaller drivers such as the RK, RL, etc. I seriously doubt
the MSCP driver could be smashed in to a 11/23 kernel and leave room
for too much else.
