I recently bought the TOS 1.4 (UK) upgrade kit. On each of the chips is a checksum. Does anyone know how this is calculated? I tried obvious things such as summing alternate bytes of the first 64K, but couldn't get anything like the correct values. (I have no reason to believe my ROMS are corrupt - they seem to work fine. I'm just curious as to how the checksums are calculated). -- =============================================================================== Andrew Dawson, Computer Centre, University College London, Gower Street, London WC1E 6BT, England.
