Got a haul of apple II stuff. Anything rare/notable?

[AutisticIndependence@gmail.com]

I have a friend that just started a tech job with the local school
district. Knowing that I am interested in all things Apple II, (and
knowing that the school is NOT and wants the junk out of there), he's
been giving me everything A2 related that he comes across.

The coolest thing so far is not an A2, but an early powerPC that is
the perfect vintage to be a rosetta stone for my Rom3 IIgs- It is
powerful enough to surf the internet, yet old enough to write Prodos
800K disks and run Apple II appleshare. So now I have an appleshare
boot A2 with access to all the IIGS software available on the net! Too
Cool!

Anyways, I have a ton of other interface cards. Most are 80 column
cards and disk II interfaces, but there are others I'm not as familiar
with. Let me know if any of these are notable (can do cool stuff with)
or rare (worth keeping for collectors purposes).

1. A G32E Adaptive Firmware Card. The internet says this is for
disabled access with a touchpad or other device? Both this and the
below card seem to have lots of RAM chips and a 65C816 processor on
them?

2. A G32 Adaptive Firmware Card- Very similar to above, but has
slightly different IC placement.

3. A fully populated "Vergecourt LTD" Ramex 128 card. 1982 is
silkscreened onto the card. I'm assuming it is a 128K ram expansion
for IIe? Looks like the card was originally half populated with ram
chips from the factory, and somebody filled in all the rest at a later
date, as the chips are from different manufacturers.

4. Applied Engineering AZ-80 Plus card. It has a z-80 processor. I
take it is it for running CPM type software? Anything cool that this
would allow you to do?

5. Apple I/O controller card 655-0101-c. Looking up the part number
somebody says this is specifically a duo disk interface?

6. Advanced Logic Systems Z-Engine card- Another Z-80 card with a very
different IC layout than the one above. A post it on the electrostatic
bag says "To Be Used With Corvis" What's corvis?
