I described that one and the one regarding Dave, to a fellow I know at

While the Massbus adapter talked SMD for all these drives, the Massbus
adapter for the RM02/03 is not the same as for the RM05. Unless I
remember wrong, they are very different beasts. And they identify
themself as the exact type of drive on the Massbus as well, and the
capacities and geometries differs, which is important, as Massbus drives
expose all these details to the computer.
The RM adapter is *mostly* the same across RM02/03/05/80, but yes I think in
each case there's at least one board that's different (later version to add
register bits for larger drives etc.). It's the same basic design though.
The one in the RM05 is mounted differently (horiz instead of vert) so you
can fit two of them into the mini-cab between two drives. The others all
had enough space under the drive itself for the RM adapter so they didn't
bother trying to conserve space.

Yeah - I was wondering the same thing. The RM80 Technical Manual doesn't seem to be online, but the RM MASSBUS Adapter Technical Manual
http://bitsavers.trailing-edge.com/www.computer.museum.uq.edu.au/pdf/EK-RMA…
has a lot of information about the RM80 too. It looks like the RM80 used the same MASSBUS Drive Control Logic box as the RM0x drives. As I remember, the RM02/3/5 were CDC 9760-something drives, which were SMD. Of course it's possible that the DEC OEM versions had customized interfaces.
The RB730 Technical Manual is also online
http://bitsavers.trailing-edge.com/pdf/dec/vax/730/EK-RB730-TD-001_VAX-11_7…
and it has a description of the R80 interface, but this version doesn't look that much like SMD to me.
While the Massbus adapter talked SMD for all these drives, the Massbus adapter for the RM02/03 is not the same as for the RM05. Unless I remember wrong, they are very different beasts. And they identify themself as the exact type of drive on the Massbus as well, and the capacities and geometries differs, which is important, as Massbus drives expose all these details to the computer.
So I very much doubt the Massbus adapter for the RM80 is the same as either of the others.
(The RM02 and RM03 is the same drive, just with different rotational speed.)
Also, the RP04/05/06 are also SMD drives inside, but with a totally different Massbus - SMD interface. And yes, as John mentioned, DEC actually did slightly change the SMD interface so that it is not a plug and play with any other SMD drives, even if other parameters would be compatible.
Oh, and by the way, I'm not sure the R80 is an SMD drive at all. Is it?

Was there ever a UNIBUS DSSI controller or were they all XMI only like
the KFMSA ? That d be pretty convenient to use either:
$DSSI_CONTROLLER <-> HSD <-> BA350 <-> SCSI to CF adapter
or
$DSSI_CONTROLLER <-> HSV <-> BA356 <-> SCSI to CF adapter
As others mentioned - DSSI existed for Qbus. But no, nothing for Unibus.
However, seems like a long way around to get to SCSI by using DSSI. Why not go SCSI direct in that case?

Awwww.
Unfortunate, but nto surprising.
I ve actually had the 11/730 for about fifteen years now I restored
it out of parts from two different 730s that were scrapped. It s been
fairly easy to keep running except for the drives, and although it s
admittedly a bit slow, it s a cool machine.
It is horribly slow... :-)

No MASSBUS controllers on the 730, remember? The only MASSBUS controllers
supported by VMS are the RH750 (for the 11/750) and RH780 (for the 11/78x).
The RH780 was also used on the 86x0 machines.
I'd love to see your -11/730 working on HECnet!
LARGO::, 2.6. It's been up many times and will be again, as long as the
current disk holds out.
Alternatively, can a -11/730 be booted over the network?
No, there's no netboot for any 7xx VAX...
Correct, for the most common definition. Of course, if you manage to start some special bootstrap program, if could boot off the net just as well as something else. But VMB on these machines do not have that support, so it's a chicken-and-egg problem most of the time.

These are available on eBay for about a $1K last I looked. You'll need
to poke around the VMS web sites for the drivers, but we had some of
these on a couple Unibus machines, including a 780 a >>long<< time ago.
I know no reason why it would work for a 730 - although you might
need to sysgen on a working system to create the boot disk.
Something like a CDU-720 will work just fine. Normal MSCP, so no special device drivers needed either. Works fine in an 11/730, or any Unibus machine in fact. Bootable on just about anything as well.

My 11/730 is not happy the electronics work great and are even

I ve never been able to find a replacement.____

I have several vintage SMD drives, including a couple of nice CDC
9715 drives, that I was thinking about using to replace the RA8x
drives. I have not one but two UNIBUS SMD controllers an Emulex
SC21 and a Spectra Logic 121 that I thought would do the job, but
after reading the fine print yesterday that turns out not to be
true. Both controllers emulate RH11s with RM0x drives attached,
which is fine if you re a PDP-11 but VMS has never supported that
configuration.____

[Before anybody says Wait RM05s are supported by VMS, that s
only partly true. VMS supported MASSBUS disks on a RH750 or RH780
controller, but VMS has never supported the RH11. Emulex actually
sold a special VMS driver for their card, but I don t have it and
besides, VMB still wouldn t support it. The Spectra Logic manual
only talks about PDP-11 OSes and carefully avoids ever mentioning
VMS.]____

I ve got some RA7x drives, but there s no easy way to mount them
or supply power to them. I m not sure if there ever was a rack
mount chassis for RA7x drives. There was for RA9x drives, but those
I don t have. I also have two RC25 drives and several AZTEC
controllers, but those drives were horribly unreliable even when
they were new. Neither works, and fixing them or getting removable
media for them is hopeless.____

Does anybody have any other ideas? Who else has an old UNIBUS
