Subject: STARLAN 10 10BASE-T hub unit doesn't like adapters

I have two somewhat old (circa 1988) STARLAN 10 hub units that
are part of our TCP/IP ethernet LAN. Our lab is wired twisted pair
with RJ-45 plugs. This is fine for our PCs with their RJ-45 port
cards, but for our UNIX boxes (Suns), we need to use AUI to RJ-45
adapter boxes.

Here's the problem. We recently bought a new (1991) adapter box from
Cabletron, but it did not work when we wired it up. We have a few
old adapters from AT&T (which came with our now defunct 3B2s (ick!)),
and some others from a company called David Systems, which work A-OK.

I am somewhat perplexed. Has there been a change in the 802.3 standard,
are our hub units no longer usuable, or am I just missing something
somewhere ?? It would seem a shame to throw out 22 usuable ports,
especially with the price of some of the new fancy-pants hubs I've
been looking at.

I apologize if these are newbie questions, or are more appropriate to
another, more wire-head hardware group.

Thanks,
