Curt:
I saw an old post of yours from 2003 included below, about the RLV12.
I am working on a hobby/project to copy a large collection of my old
software from RL02. I was wondering if you ever got your RLV12 to work
with the VAX? I was under the impression that because the RLV12 controler
was old PDP11 DMA it could not handle the VAX MMU, so the DMA would write
the data to the wrong area of memory? I do know that DEC never supported
the RLV12 with any QBUS VAX.

Hi,
I've got an RL02 connected to my Vax 4000-200 through an RLV12 QBus
controller.
The Drive is spinning up fine and the Ready light is Lit, the Fault light
goes off once power to the Vax is started and doing a SHO DEV at the
Chevron
prompt and within OpenVMS both show:
RLV12 Controller 0 (774400)
-DLA3 (RL02)
Which looks great from my perspective, the drive ID plug is a 3, so DLA3
makes
total sense. In the SHO DEV within OpenVMS does
display the drive as
being
online.
So my problem is with MOUNT, everytime I go to mount the drive the system
simply hangs and never seems to complete the mount, I end up having to
CTRL-
BREAK to Halt the system back to Chevron and b up
again from my DSSI DIA0:
Anyone have any idea's what I'm doing wrong or what may be wrong???
I've tried with a /FOREIGN too since this platters are from an 11/730
and many
of the handwritten labels on the disk paks say RSTS on
them, so I wasn't
sure
if it was a format issue or something, I could really
use some
help/advice from
anyone with a lot of experience with the quirks of the
RL's.
Thanks much,
PS: If anyone has an RK05 or RK07 DECPack for sale and possibly an
RKV11D Qbus
controller I am in the market for one.

I'm not Curt, but I'll answer anyways. BTW, your email address looks
familiar. ;)
The RLV11 doesn't work on a VAX, because it can only do 18-bit
addressing, not 22-bit addressing. The RLV12 works fine on a VAX, as
SRM and VMS both identify it, and use it properly. I've made images of
quite a few RL02 carts using VMS's BACKUP/PHYSICAL command.

I have a MicroVAX III that specifically exists for this (the downside
being it's so far back in my one storage unit it isn't funny). I've
had both RL01 and RL02 drives hooked up to it, and read both types of
carts successfully.

Depends on the operating system. NetBSD uses
only 18 bit DMA addresing
for both UniBus and QBus. (NetBSD treats UniBus and QBus (nearly) as the
same). Any further addressing is done with the UniBus map / IO-MMU. So
with NetBSD you can use a RLV11. I know this as a RLV11 is mounted in my
VAX 4000-400, driving a RL02. :-)
The problem with the RLV11 is: It is a two card set. It needs two QQ/CD
slots and uses some pins on the QBus for test signals, that are used for
Q22 signals also. I had to open some traces on the board to make it work
in the Q22 VAX.

Hi Todd,
Like others who've posted I've got an MVII running an RLV12 for VAX access
to my RL02s. As for DEC support I'm fairly sure the UK arm of DEC did,
certainly in the mid 1980s we had, well, the same VAX I've got now running
the same RLV12 with the same RL02.
DEC engineers were fine with it, even though I'd built the 3 RL02s into a
cab we'd rescued and I'd monikered it as an SA3RL02 :)
