We have an ethernet in our computing centre connecting several Vaxes.
Now we want to extend the net to the computer science dept and add a
Pyramid 90X, Sun 3/50, Sperry Explorer and Kinetics box. We're having
problems locally confirming the compatibility of equipment and would
appreciate help from anyone who has been the route with at least some
of the stuff.
The Vaxes all run VMS, DECNET and ethernet 2.0 with H4000
transceivers.
The Pyramid is a 90X and predates the development of the IOP. The
Pyramid board goes in a multibus adaptor. They claim ethernet 1.0
compatibility. I can't find the details but I seem to recall that
means 16 bit addresses which will play havoc with the Dec kit. Is it
really ethernet 2.0 or is my memory wrong?
The Pyramid board only does ethernet, not tcp-ip. We're attracted to
the excelan board but to my knowledge there are none in NZ so that
may be a problem. Has anyone put an excelan board with tcp-ip into a
90X and what problems were encountered?
The Sun is a 3/50 and we're confident that it will talk to the Pyramid
(NFS and all that). As far as we can tell they do the protocol
details in software and can handle most any variant of ethernet
although the local supplier insists its straight 802.3. (That would
cause the DEC gear with H4000 transceivers to fall over according to
DEC.)
Finally we have the Sperry (TI) Explorer. We have the documentation
for the controller which claims its 802.3 but gives an ethernet 2.0
packet format! Can someone confirm its ethernet 2.0?
(We haven't bought the Kinetics box yet but if anyone can forsee
problems please let us know.)
Please reply by email and thanks in advance for any help.
