Sampsa, you could join easily if you pick up a low-power older cisco
router for absurdly cheap if you don't care about speed. (like a
2524...10BASE-T! It'd be perfect for IPX and low-bandwidth DECnet
tunnels!)
There used to be Pathworks for Novell Netware. A Netware (3.12) server instance running on VMS. It was talking IPX.

Eeek!
You'll need to poke around the VMS web sites for the drivers
Looks like it does MSCP - I don't know why you'd need special drivers
unless maybe to support non-standard sized drives.
That shouldn't matter either. MSCP gets the device size from the device; one of the big points of MSCP is to do logical block addressing and leave geometry as a device detail. I'd be surprised if VMS got this wrong...

There has been a SA7x rackmount enclosure for RA7x disks. About the same size as RA9x enclosures. Very similar to SF7x enclosures.
I think you could find SA7x's from the large brokers who have old DEC hardware for sale. I guess the pricing would be reasonable.

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 VAX?
What are you doing to disk drives?
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.

but an RM80 will work fine off of the RB730 controller.
Not exactly - I knew that the R80, RA80 and RM80 are all the same drive except for the personality modules. Certainly the HDAs are all the same. The R80 essentially has no personality the RB730 does all the work. I guess the RM80 must have the MASSBUS controller in a separate box? So the actual drive is like the 730 it has no personality module inside?
My first home machine was an 11/725, to which I added an RB730 controller ,
and I used it with an RM80 for a number of years, until power problems killed
a bunch of boards in it.
Do you still have it? I have some spare boards (or alternative, I also have a 725 that needs a new chassis :-)

You are probably already aware of this, and they probably are not be any easier to find now than an R80, but an RM80 will work fine off of the RB730 controller.
My first home machine was an 11/725, to which I added an RB730 controller , and I used it with an RM80 for a number of years, until power problems killed a bunch of boards in it. I hated losing it, since I had also added a VAXstation 100 workstation peripheral to it - at the time it was a pretty exotic setup for use at home. I'm still hanging on tothe VS100 gear, in case another Unibus VAX comes my way.

Unibus to SCSI is probably your best bet.

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.

Well I suppose I could try to find one - could roll out a Netware VM + NEXTSTEP does Netware file sharing..

Sampsa, you could join easily if you pick up a low-power older cisco router for absurdly cheap if you don't care about speed. (like a 2524...10BASE-T! It'd be perfect for IPX and low-bandwidth DECnet tunnels!)
