OK here is acuurately:

00/017D: 00 00                  BRK 00
 A=FF00 X=00C9 Y=0000 S=0171 D=0000 P=B0 K=00 M=0C Q=A8 L=1 m=1 x=1 e=1

I know I got it right this time, I set my GS right next to my Mac and copied it
directly, instead of stupidly jotting it down on a piece of paper and walking over
to the Mac to type it out. I double & triple checked it.

The big error was I misinterpereted my own handwriting and got a one instead of
the first slash and a zero instead of the first D. The Y=0000 I wrote down as
Y=0010, could this have changed? More likely another mistake on my part. I don't
know if it matters, but the B in BRK 00 should be directly over the S in S=0171. I
don't know if it will stay that way in transit.

I'm anxiously awaiting your interpretation of this, David.

Once again, my own stupidity catching up with me. I compared the card to a picture
of a Rev C card that was sent to me, ignoring the number on the chip. It is in
fact a Rev. B. card.

Where can I buy a Rev. C. EPROM?
