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.
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.

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
