What Is This?

Yes!  I found one of these, but mine was missing the donut!  Broken off by heathens I'm sure!   CC was nice enough to let me know it's just a ferrite core with a single wire running through it.  Mine's obviously been reworked to disallow for office use.  Guess I'll have to use it at home only.  lol!  :lol:

I've got one of those too in my Quadra 700, have the software if anyone needs it.  Never got it to work, after many attempts.

Interesting. Those look more like interposer cards for testing chips rather than than a commercial upgrade card.
