Ah, on the eBay store. I only ever saw the printer cards on the web
store in recent times.

I can't find one of the actual cards that is modified, but here's what
I think is the key, from the notes:

A line runs from RA1 (pin 10 on the edge connector) to pin# 13 on
which should be a 74LS175. I don't have a PCB to look at.

Looking at a datasheet, Pin 13 on a '175 is D4, the corresponding
outputs on that would be pins Not Q (Pin 14) and Q (Pin 15)

The Super Expander E should have pin 15 hooked up to whatever is right
above it.

Pin 14 should be floating.

Hooking pin 14 and 15 together should result in a card that works with
either the Super Expander disk, or the AE AppleWorks Expander utility.
(and standard AW3 & up without patching anything) Likewise, if you
connect one pin and float the other, you'll have just the opposite
effect. I do recall leaving it set to both with a glob and having it
do exactly that, work with everything.

The visual memory that I have is that it was two pins side-by-side and
that jives, the only thing I question myself on is that I want to say
those pins were at the "end" of the IC, but looking at the pinout
thats not possible as all the corner pins are clock or power.

Or course, all of this information is provided without any warranty
what so ever as it's all 17-18 year old notes.

Damn, it's been that long?
