Hello all,
I am in the process of acquiring a MivroVAX II, and I
have decided that I would like to connect the MicroVAX to the
PDP-11/84 and the three AT-clones in my basement via ethernet.
Currently everything is standalone, so I have to start
from scratch.
I have looked through some old DECdirect catalogs to
get an idea of what to look for, and I think I found it:
(pardon the ASCII representation)
Thinwire ethernet with 'T's
50ohm __ _______ ______ ______ ______ ______ _____ 50ohm

| | |
DEQNA DEUNA DSRVA-AA
MVII 11/84 with assorted
(BA23) terminals/
printers/
and a modem for
dialing out
What I am looking for is just about everything you see in
the diagram. I need a DEQNA (I will be running VMS 5.3),
DEUNA, three DECnet-DOS supported boards (like the DEPCA
or 3COM Etherlink boards), DSRVAA DECserver 100, three
DESTA's, and assorted wire and T's.
Ethernet II is fine with me, as I won't be running anything
new enough that will be 802.3 (I don't think so anyway,
but I could be wrong.) .
If anyone has any of this equipment sitting around,
let me know. I don't have an exhorbitant amount of money,
but I do know a bargain when I see one.
And if anyone has any comments/suggestions about Ethernet,
please let me know.
Thanks,
Chris Kalisiak

I'd give up on the idea of using DESTA's - for a setup such as yours they are way too expensive, and they need AUI cables (the 15-pin cables) to con- nect them to the controllers. MTI's MESTAs are better, but they need a big dose of reality in their pricing. Talk to Allied Telesis at (800) 424-4284 about their "CentreCOM MX10" transceiver for $99.95. Next, take the money you're saving on DESTA's and buy a dead DEQNA from somebody. Call DEC at 800-225-5385 before the end of this month and get the $660 trade-in to a DELQA. VMS really doesn't like the DEQNA any more, and will soon start to ignore it. If you're going to be using Pathworks (or whatever the call it today) on the PC's, get any Ethernet card that's NDIS compatible. Everex SpeedLinks (800) 821-0806 are fast, inexpensive, and reliable. If you absolutely must have a DECserver 100, ok. I'd wait a while for the 200's to come down. Of course, the DECserver 200/DL (data leads only) has been discontinued by DEC and is pretty inexpensive these days.
