[comp.sys.apollo] Apollo series 500 memory???

kmont@hpinddacup.hp.com (Kevin Montgomery) (08/18/90)

	A friend of mine just bought a used Apollo 500 series machine and
has been running Domain on it (and was quite pleased!), but unfortunately
is running with X on only 4 Megs!!  (so he's really thrashing the disk and
performance is very close to intolerable).  So, does anyone in Apollo-land
know where he could pick up some memory that would fit this old, but fun,
beast?

					thanks in advance!

It depends entirely on *which* 500 series machine he has ...
DN550's and DN560's are limitted to 3 MB of RAM total (2 MB
on the CPU board and 1 MB on the VME(?) board). DN570's,
DN580's, and DN590's are also limitted to 3 MB unless they
are Turbos (ie. DN570-T, DN580-T, or DN590-T), in which case
they have at least 8 MB of memory. Non-turbo DN570/580/590's
can be upgraded to Turbo models, but that involves replacing
the CPU board.
