Although AT&T won't support it, you could use the Intel RAM
expansion cards.  We had a prototype here that came with one
of their cards; it had 8 MB of soldered on 1 MB DRAMs (72
DRAMs).  They were soldered on on our card, so it looks like
you have to buy what you want, and if you want to add more
later, you have to buy a new card.  Kind of makes the AT&T
card look really good (:-).  The particular model I used was
in a 6386/25, and worked in both the prototype and the
production models.  I don't have a part number for the Intel
card, but I believe it was for the 302 computer.

You could also use plain AT RAM expansion cards, but they
probably can't take advantage of the RAM cache, and they
will be slooooow.  Once, again, AT&T wouldn't support that
configuration, since we sell a memory card ourselves for
that purpose.
