This link was already in my first post. Nothing special on the
Oh I'm sorry Holm, somehow I missed that part of your first post.
Hmmm... Powered it up..
I've got the stairways down to a room where I store seldum used things and
grabbled out an PC that I'm build to read/write 8 Inch Floppies, it is a
PIII/500 or so..
Opened it up, and put in The rtVAX Card in one of the two ISA Slots from
the Motherboard. Switched it on, Saw an "E" on the TIL311 and than BOOOM,
white flash out of the PSU.., Fuse for the Mains circuit blown. (not
really, it is a resettable 16A 230V device).
Ok, pulled the broken PSU (Source for some colored DC Cables) and mounted
another one.. maybe there is something true on that urban Legend that one
should let cold devices acclimate a little before switching them on...Ok,
maybe next time..
Ok, switched on again, Selftest on The TIL311 from F down to 5 and there it
sits for ever. Pulled out a cable adapter from MMJ to DB9 that I used in
conjunction with an DECServer 300.. Nothing on the line, same with the
other MMJ Connector. Switched off and dismounted the Card.
At first, that are no MMJ Receptacles there, that are normal symmetric
Telephone like Receptacles with 6 prongs 8in them. Looked closer to the
board and founf a 75C1406, Datasheet archive ... aha.
Found the following connection for the two Receptacles:
1 - NC
2 - GND
3 - RxD
4 - TxD
5 - GND
6 - NC
Ok, made an Adapter to DB9 again an looked to the Seyon Terminal:
rtVAX 300 V1.2
E...D
...and there it sits for a while...
Finally
E...D...C...B...A...9...8...
I now hold the ISA Board in my Hands. This thing is
labeled "AEON Systems
Incorporated, ISA300, Made in U.S.A."
...anything known about this?
It seems that there is still a company named AEON Systems on the net,
mostly selling some IBM Stuff.
Maby I should aske there nicely...
Hey, my VME rtVAX-300 board was made by that company as well!
Can you take some pics of that board? I find the idea of a VAX on an
ISA card to be rather freaky but intriguing. 
backside, Two MMJ connectors, 2 pushbutton
Switches ( Reset, Halt?)
and a single TIL311 are on the bracket side..
In what you are specially interested?
My AEON VME board has nearly the same complement of buttons and
connectors, and a TIL311. One difference seems to be your board's two
MMJs and my board's single RJ45. My board also has an AUI Ethernet
connector.
I'll try to power up that thing tomorrow..
Sounds good. I'm interested to know how you make out.

Hmm.. have to connect something I think...
Is there someone that thinks that he know that the Pinout of the Ethernet
Connector ist the same as on a DELQA for example? There is an Ethernet
Transformer on The board next to the connector...no AUI at all? I think the
Transformer is part of a PHY already...
