What's this AppleIIGS card?

[cripps@mda.ca (Andrew Cripps)]

I wonder if anyone can help me. I bought an old AppleIIGS (Rom 03, 2.5MB RAM)
for $30. It came with some strange cards installed, and I would like to identify them.

In one slot, there is a "FingerPrint GSi" card, which has a little tiny fingerprint
switch attached to it. If you press this switch during startup you get into a sort
of typewriter application.

Then there is an Echo II card installed. with an Echo box attached to it through the
back plate. What is this card for? The Apple IIGS seems to have a built-in speaker
anyway, and there is a sound-out port on the motherboard.

There is a weird "Adaptive Firmware Card" produced by Don Johnston Development
Equipment Inc. Attached to it by cable is a box which sits on the side of the Apple IIGS
case. The box has an on/off switch, a centronics socket and two mini-jacks labelled "switch 1"
and "switch 2". What's it for?

Finally, attached to a socket on the motherboard labelled "Games" (board reference is J21),
there is a chip with a cable coming off it, out of the back plate and terminating in an
RJ45 adaptor. What the heck is it?

Please email with your responses.
Thanks for your help.

Andrew
