I believe the Needham software produces different checksums depending on the
device selected. If you ensure an 8 bit EPROM is selected of the correct
size then the checksum generated should match the Checksum - 16 with Hex
Workshop ( when in hex mode and 1 and 2's compliment turned off ). If you
zero the first 6 bytes in Hex workshop then the checksum generated should
match GME.
