I beleive Digital's MV7 (I think) does support RDs. It is mentioned in
the 11/23+ Owners Manual. I'll have to check. I guess this version
isn't in the archive ...
Cheers,
Bob.

What about Digital's MV7 (or whatever it was called). This is
mentioned in the 11/23+ owners' manual as supported. Thus it must run
on the 11/23+ and support RD series disks. It is basically Bell Labs
version 7 I think.

OK. I guess 2.x BSD (x>=9) requires separate I+D space? That would
rule out the 11/23+ I think.

Yes. I can believe that. Looks like writing my own driver would be no
fun at all!

The 11/23+ has plenty of address space (22 bit), but mine only has 128Kw ...
Cheers,
Bob.

True - Ultrix-11 (what MV7 was called later on) does have MSCP
support in it. I've not looked at how they handle the rather
prodigious data space requirements (~2kb per controller) yet.
Cheers.

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.
