Re: Signature Analysing Question

Hmm, you should have information on the schematics for the signature
analysis of the mathbox boards. This is the same for your HP as it is
for the Cat Box. The beauty of the Cat Box is it hooks up directly to
the edge connector of the game baord and one can do a checksum or ram
test without removing the parts. This does NOT always work, I have a
Sprint II that works fine, yet the Cat Box gets erratic reading on the
CS's of the ROMs. sheesh...
