I have this card, software and manual. 

It's an 8 chip card but all the numbers have been sanded off

The software is copy protected but the card will duplicate it. Unfortunately
disk images don't work.

The manual is the same one that came with the EDD4 software. It's about
160 
pages and has a small section on the card plus mention ofit here and
there 
in the manual. There were also a few looseleaf pages on stuff that came
up 
after the manual was printed and some corrections

The manual says the card is able to reliably read "hidden timing BITS
found 
between the raw disk Bytes"
