A few questions about RAM cards:

1) The Oxen Industries (now remarketed by MC Pricebusters) "Super
Expander E" is marketed as a clone of the AE RAMWorks card.  However,
I am concerned that the Super Expander E would not be recognized by
non-AppleWorks programs (the card comes with software for patching AW,
but not for patching other software).  Is the Super Expander E
unrecognized by other software that would normally recognize an AE
RAMWorks card?  e.g., CP/AM, some of the Beagle Bros. programs that
utilize expanded RAM, etc.?

2) Can you use both a RAMFactor and an Aux card at once in a //e?
Would the total available RAM reflect both cards, or just one card?

3) Can you use both a RAMFactor and a Mem-slot card at once in a
IIgs?  Would the total available RAM reflect both cards, or just one
card?

4) If you used an 8-Meg Mem-slot card and a 1-Meg RAMFactor
simultaneously in a IIgs, then would the total available RAM be 9 Meg
(or nearly 10 Meg in a ROM 03)?

Thanks!

You can have more than one memory card plugged in but only one can be
used for expansion RAM in appleworks and the other as a RAM drive or
you can have two RAM drives.

A Ramfactor card can never be used as expansion RAM for programs, only
as a data storage media.

Not totally true. AppleWorks 3 and higher will automatically work some
voodoo to make a larger AppleWorks desktop with whatever free memory
it finds in a RamFactor (or any Slinky-style) card. For example, if
you have an empty 1 MB RamFactor, AW3 will report a Desktop size in
the 900KB range. However, if you fill up a 1MB RamFactor with about
750KB of stuff, then AW3 reports a Desktop size around 250KB or so.
All through college, I ran a //e with a 1MB RamFactor loaded up as a
ramdisk with about 750KB of stuff like ProDOS, AW3 and lots of Timeout
stuff, ProTerm, ProSel, and some development tools. I would leave it
on for weeks at a time to keep the ramdisk populated, and I still had
a large AW3 desktop even though I only had an extended 80-column card
in the AUX Slot.

Today, that //e now has a 1MB RamWorks III card in addition to the 1MB
RamFactor card. When I load up the RamFactor with its 750KB of stuff
and run AW3, AW's Desktop is now close to 1MB. Conclusion: when AW3
and later finds both an AUX-Slot memory card and a Slinky memory card,
it will use the AUX-Slot card's memory for desktop expansion.

As I recall from my time at Beagle, AW3 can only use one memory card
for memory expansion.

That's correct.  It decides at load time which (single) memory manager
segment to load, based on the cards it finds.
