Hi,
The answers in a nutshell:
a.) Yes it works
b.) The PMAD-AA has a AUI aka Thickwire aka 10Base5 interface only
so we need external transceivers for 10Base2.
Thanks to the following people for their fast replies:

Here is my original posting followed by the answers I got.
Thanks again everybody.

Hi,
We are in the need of adding an additional Ethernet interface to four old
DEC3000/600 machines. After a short web-search I figured out that a
PMAD-AA is what we want and I already got a reasonable price quotation
from a US dealer.
Before purchasing, though, I just want to make sure that we won't run into
problems with the following configuration:
- DEC 3000/600, latest firmware
- Digital Unix 4.0D, without any patch kit
- PMAD-AA Ethernet card as le1 additionally to the built in
Ethernet as le0
Is anyone running such a configuration (or a similar one) ?
As an aside, can anyone tell which Ethernet interfaces the PMAD-AA
supports? I mean: AUI or 10base2 or 10base-t or all of them?
Thanks for any informations.
Tom

Works fine....
Make sure to have the network CONNECTED when you are getting the card to
recognize itslef. It wants to be plugged in either to a network device or a
loopback to pass it's diags.

We have a few of these beasts, and they still work.
Some of our 3000/600's have the PMAD-AA cards; and I am planning
to move some of these cards from even older Ultrix boxes into others.
We mostly use the secondary interfaces for backup etc.
The PMAD-AA is your basic thick wire interface, you will need a transceiver
to connect to a 10baseT network.
The ONLY faster solution is to do FDDI; there are NO (and I checked recently)
100Mbit boards. There are TurboChannel FDDI cards; we once tried them out
on both Ultrix and Digital Unix, but never used them. They are DEFZA-AA
DEC FDDI Controller 700 cards; should show up as PMAF-FA's, see
/sys/data/tc_option_data.c
They may be hard to track down in guaranteed condition; I have two loose
(and two others in machines, cards not in use) whose condition is not
guaranteed, but I might be willing to give them away if you want to play with them.
I think they need a dual attach FDDI ring....

Sorry, we are not...

But you might find more details of your NIC here:

I hope this helps. Good luck!

What sort of price ? What dealer ? I have been trying to track down
one of these for our 3000/700 and Compaq don't seem to be responding
to my request (too hard basket). I currently have a unit on loan from
a friend.

I have a 3000/700 - it is running 4.0B patch kit 6. Putting the le1
in enabled me to split my network and reduced the traffic back to
workable levels :)
I hope to be embarking on 4.0E this weekend for this machine in case
you're interested.

It has an AUI port only so a transceiver is mandatory in most cases :)

Hope that helps.

Thomas,
That has been done many a time eg. for firewalls.
>From memory the PMAD-AA is AUI + 10base-t, but this is from memory only.
If you do not get answer another way please drop me an email.
I certainly have both the real card and instruction for it buried somewhere
in my office so I can check it for you.
I hope this helps.
Regards,
Chris
