[comp.sys.mac.misc] Findings on Mobius 030 accelerator w/SE, PMMU and VM

sam@skybridge.SCL.CWRU.Edu (Sam Chan) (04/20/91)

Hello Netters,

   Thanks for all the replies to my question concerning
the Mobius accelerator/video card and the PMMU option
for an SE.

   Many people wrote that the SE can only address 4MB of
memory because of its ROM. Mobius stated that you can put
4x2MB and 4x4MB simms in its boards but the SE will only
address 4MB regardless. The rest of the RAM after 4MB is
used as a RAMdisk. Mobius hopes that developers out there
would write some codes to allow SE owners to address up
to 16MB of RAM with their board.

   On virtural memory, Mobius said that the PMMU option
will work with Virtual 2.0 and allow the SE to address up
to 16MB of VM, 4MB RAM + 12MB VM, but they did not mention
anything on System. 7.0. Pat Kuras, KURAS@AplleLink.Apple.com,
wrote that Apple does not expect MacVM to work with third
party boards.

   Since my work deals mainly with DTP and graphic design,
I really need fast mother board memory in the area around
8MB or so. Plus I have been hurting for color...hmmm, maybe
it's time to get rid of my SE and get an Si. (I really want
a FX, but I don't believe in Santa ;-)) Any suggestion?

   Thanks again!
