The Question is:
My question pertains to my VS4000/VLC, not specifically VMS. Sorry, but I
have nowhere else to turn it seems. I've tried the newsgroups, internet
searches, the Compaq website and DEC equipment dealers to no avail.
I have a VS4000/VLC (model VS48K-CA) and a VRT19-HA monitor. I can and have
run my system with a VT320 monitor and installed the hobbyist OpenVMS v7.2
successfully (although it told me I had an Alpha, not a VAX!).
My issue: I can't find the right video cable anywhere!!!! :( My VLC has a
LR-8 PLN FB-V1.1 graphics card with a 15 pin SVGA female socket on the back
of the box. The 'standard' for VLCs it seems is a 'D' socket with 3 BNC
connectors. That's not what I
have.
I got a generic 15 pin to 5 BNC cable from Best Buy. It fits but all I get
are fuzzy grey lines on the screen. This indicates the horizontal
(composite) sync is not right, I think.
I need to know:
1. what type of graphics adaptor do I have? i.e. will it drive the VRT19-HA
or is it realy a VGA adaptor? (I have tried two VGA monitors on the box
unsuccessfully)
2. the pinouts for the socket on the VLC so I can hack the generic cable I
bought, if possible.
3. the part number for the correct DEC cable if that's my only option.
I don't own a VT terminal so I haven't able to use the VLC since September.
I'd realy like to use DEC Windows though which is why I want to get the VRT
connected.
Please help.

The Answer is :
The VAXstation 4000 VLC series used the following video cables:
Manufacturing Orderable Video
Cable Part Cable Part Controller
---------- ---------- ----------
VAXstation 4000 VLC 17-02906-01 BC29G-09 PV31G-AC/AD
Color/Greyscale 17-02906-02 BC29G-03 PV31G-AC/AD
Color/Greyscale 30-34762-03 BCC27-05 PV31G-AB
Color/Greyscale 17-01992-01 BC23J-03 PV31G-AA
Various of these cables were shared with members of the VAXstation
3100 series.
The VAXstation 4000 VLC series used the following video controllers:
Video Controller Video Manufacturing D-sub
Controller Description Resolution Board Part Connector
---------- ----------- ---------- ---------- ----------
PV31G-AA HR-8PLN FB 1024 x 768 at 72Hz 54-20772-01 15-pin
LR-8PLN FB 1024 x 864 at 60Hz
switchable resolution... switch set on: 72Hz, set off: 60Hz
PV31G-AB LR-8PLN FB 1024 x 768 at 60Hz 54-20776-03 3-pin coax
PV31G-AC Mono-4PLN FB 1280 x 1024 at 72Hz 54-20776-01 3-pin coax
PV31G-AD Mono-4PLN FB 1280 x 1024 at 66Hz 54-20776-02 3-pin coax
The cable pinouts are not readily available to the OpenVMS Wizard.
The PV31G-AC and PV31G-AD are compatible with the VRT19-HA video.
