Utilities/!CRC/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

!CRC - Perform a CRC check on your files ================================================ written by Paul Vigay �1990 This utility will calculate a 32bit CRC value for any given file. To use, drag a file either into it's window, or onto it's icon. You can adjust the length of the file by clicking on the left and right arrowicons, to allow for spurious bytes being added to the end of files after downloading from bulletin boards etc. Click on OK to re-calculate the CRC value. This file was written to benefit Micronet subscribers, who may verify downloaded Telesoftware against a published checksum value. If you have any comments and/or suggestions, or find any bugs I haven't listed, then please contact me via the following sources: Paul Vigay C/O 14 Victory Avenue, Horndean, Portsmouth, Hants.
