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.

X | , 8 X �� � VsyncPatrol Vsync Patrol 1.01 (26 Mar 1993) VsyncPatrol � VsyncPatrol_SetSWIbase e8 � Vsync Patrol provides more versatile vsync waiting. When the SWI "VsyncPatrol_Wait" is issued, the module returns after R0 vsyncs have passed since it was last called. On return, R0 contains the number of vsyncs which have elapsed since the previous call. Public Domain by A.Southgate sets the swi base number for this module. The default is &4C0C0 <number> IGNVsyncPatrol Wait GetAddress c P @-� �� �� ��! �? ��<"� ��� @-� ��8�� �� � ���� � ��� @-� ���� � ���� �� � ��� P�� -� �� �� �� ���� [� [� O��� -�( � ��4 � A� P������0� 0��0�� jX � P���` �d � @��� ���� ������f Unknown VsyncPatrol SWI. �� ������f Excessive Vsync wait. or
