Hi,

The board has a sticker saying "30C" just under the serial number,
with 01-W3269F printed on the card next to it. I am assuming that
is the revision.

The chip has "XC821ZP50B" printed on the top, so I guess that trailing
B is the revision you are referring to.

The processor isn't socketed, so unless there are some workarounds
available, this board may not be as useful as I had hoped :-/

Was it just data cache, or were there other flaws as well?

Regards,
DigbyT
