Apple IIe 1 Meg Memory Expansion Card.
Robert J. Stevens
Apple II Memory Expansion. How can one tell if the Memory is there. I am
a complete DUD when it comes to Apples. I bought this IIe to run the
FAIRY Chip Checker I bought years ago [Now I can't find the diskette
that runs the card]. Also can these cards be cascaded and which slot is
the best to use???

It shouldn't be confused with the memory in your IIe Auxilary slot, the IIe
basically sees it as a storage device not memory. With very few exceptions
it's only used as a ramdisk. Some copy programs will use it as a buffer.
Later versions of AppleWorks can use it and earlier versions can be patched
to use it. A few programs load themselves onto it to cut down disk access
time but that's really just the program using it as a ramdisk. Just about
any
slot except 3 should work fine. While you could fill your slots with these
cards each card will be an individual ramdisk. A program like Copy II Plus
will see it.

Is there a true, auxiliary type 1 meg memory card for the IIe, then? Or is
128k the best that I can hope for on my IIe. I have a 128k memory card,
rather than an 80 column 64k expander. Would this card also be considered a
ramdisk type card?

Yes, but not from Apple. The most popular is the RamWorks cards. Most
you'll find are 1 Meg cards, but 512K and 2 Meg expansion (above the 1 Meg) are
available but VERY hard to find. Checkmate and a few others made card, but the
Applied Engineering RamWorks card is the easiest to find. I have several
myself.

There are many. I have a Sequential Systems Meg80z which is a 1MB //e Aux
slot card. AE made Aux slot cards that went past 1MB.
They can be used as a RAMdisk with appropriate software but cannot be booted
from unlike slot based cards (and the //gs memory expansion card).

you had the expander module could be expanded to 3 mb. Checkmate also
made one that they advertized that with a daughtercard could be expanded
to 17mb. MC Price Breakers still lists 1mb Auxiliary slot cards.
The Auxiliary slot memory is a bit different from a regular slot memory
cars. The processor can use this memory to run programs by accessing
the extra memory via bank switching. However unlike the Apple II
memory expansion card the IIe doesn't automatically see this memory.
You need to run software to set it up as a ramdisk. A program must
also have the necessary code allowing it to use this memory. If it doesn't
then it's effectively not there.
Your 128k 80 column card could be used as a ramdisk with the right
software but likely isn't one unless you run that software. Problem is that
that size of card makes for a fairly small ramdisk. Maybe someone can
point to a program that"" let you use all of the Auxiliary slot card as a
ramdisk.. The ones I've used leave 64k of Auxilary slot memory alone
and turn the rest into a ramdisk, which in your case would only give
you a 64k ramdisk..
Some of the regular slot cards such as the Saturn 128k came out before
ProDOS and weren't compatible. To use them at all required special
software.
AE set the standards for Auxiliary slot memory cards. So if a program
recognizes any extra Auxilary slot memory, it'll be the cards using the
same arcitecture as AE did. At one time I used to have a Titan 384k
Auxiliary slot card that used a diferent system and no program would
recognize the extra memory on it without being modified.
