OK, here's what the Sirius RAM IIGS Mini-Manual has to say about it...
I include all text as is, including grammatical errors!  I should point 
out that I only have a Rev.C SCSI so cannot comment about RAMFast etc. 
compatability.



This simple sheet explains everything you need to know to use your new 
Sirius RAM IIGS 1-8 meg RAM Expansion.

The Sirius RAM IIGS is 100% DMA compatible.  It has been tested with both
Apple High Speed and RAMFast SCSI cards as well as other DMA peripherals 
such as the VisionPlus Video Digitizer.  The Sirius RAM IIGS can be 
expanded up to a total of 8 megs, one meg at a time.  There are no dip 
switches or jumpers to configure.  Simply install the RAM and your on 
your way to Sirius computing!  The banks start at the lower left corner 
of the card, meaning bank 1 is in the lower back corner of the IIGS.  A 
note to ROM3 users: only 7 meg is supported since you already have 1 meg 
on your motherboard.  The first SIMM socket will be empty.  This is OK.  
If you install the card in a ROM 3 system in the ROM 1 configuration you 
will have one less bank of RAM available to you.

Sirius RAM has been tested with AppleWorks 3.0 & up, AppleWorks IIGS 
v1.1, Platinum Paint 2.0, HyperStudio 3.0, HyperCard IIGS, GNO/ME 2.0.5, 
the Orca series & Merlin 16 to name just a few.

A few notes about DMA compatibility:

Only the first 4 megs of EXPANDED memory are DMA compatible.  This does 
not include RAM on your motherboard which is also DMA compatible.  The 
computer hardware is well aware of this an no special work arounds are 
needed.  This means it will do DMA when it can, and won't when it can't. 
You can use all 8 meg of RAM and have the Apple High Speed or RAMFast 
card configured with DMA active.



My opinion?  GET THIS CARD!!!!
