ChipInfo/7450
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.

<h3>7457</h3>
Frequency divider.
<br>
Can generate one second timing pulses from 60 Hz.
Two '57 devices may be interconnected to give frequency division of 3600 to 1,
1800 to 1, 900 to 1, etc.
Features a reset pin that is common to all three counters.
