The are 20 pins at the RA7x OCP interface. I found RA81 OCP
pins, but this is different. Can anybody help with a pinout or
link?

If you want RA81 details, I assume one of these manuals
at least can help:
http://vt100.net/manx/search?on=0&cp=1&q=ra81
I'm reasonably sure that I have at least one
RA7x manual scanned somewhere but it does not
appear on Manx:
http://vt100.net/manx/search?on=0&cp=1&q=ra7
I'll see if I can dig it out and let you know.
Remind me in a few days when I've forgotten :-)

Thank you, Antonio. What I want was the RA7x OCP pinout.
None of the mentioned documents gave that information. I think
what I need is something like:
MP-01428, MP-01429, MP-01434, MP-01435 or MP-01439
This are Field Maintenance Print Sets for RA70, BA27, RA71/72,
SA7x or RA73 respectively. If not scanned (what I assume) can
please somebody of the manual owner have a look for the OCP pinout?

Two manuals that don't help with this specific query but
are genrally useful for RA7x drives anyway are:
EK-ORA7X-SM-002 RA7x Disk Drive Service Manual
EK-RSA7X-PG-002 RA7x/SA7x Pocket Reference Guide
About the only thing they do not list are pinouts for
an OCP. So you may be reduced to waiting for someone
with one to buzz it out. There are two variants of
the OCP - the one used in the BA200 series chassis
and the one used in the SA7x enclosure (in an array
of disk drives in a rack).

One other thing I've just realised is that there are
at least two more manuals available that describe the
SA7x enclosure:
EK-OSA7X-SM. C01 SA7x Enclosure Service Manual
EK-OSA7X-UG. C01 SA7x Enclosure User Guide
Neither of these seem to have an answer for you
(but please check for yourself, as I just skimmed
them quickly), however, they do provide a bunch
of useful information.
In addition, there are lists of related docs at
the beginning of the each of these manuals, so
you will at least have an idea of what you should
be looking for.
I don't think that my MicroVAX 3600 has an OCP,
but if it does I'll see if I can get to it and
buzz it out.
