What we need is for some bright person to write a simple utility that converts data files to signatures. The signature formula is fairly simple and if combined with Bill Ung's ROMSUM would be a nice tool for our package. If you don't know ROMSUM it is a dos utility that will give a checksum listing plus the ROM size for a single or group of files... The Signature process is a CRC process that uses the following feedback equation: X(to the 16th) + X(to the 12th) + X(to the 9th) +X(to the 7th) + 1 or P(X) = X(15th) + X(9th) + X(7th) +X(4th) + 1 So who wants to make a simple (not for me!) binary program that allows one to input a file and outputs it's signature?

Anyone written any test scripts for these or at the very least have some checksum signatures?
Thanks, Kev
