Convert 6 cyl tacho for use with 4 cyl

[Andy Whittaker - Chester UK]

Peter,

Obviously you need to divide by one and a half.

Use an 'edge-triggered' binary up/down counter set to count-up. This will
effectively multiply the input square-wave by two. Then, connect an AND gate
between bits 0 and 1 of the counter, this will divide by 3. This should then
give you the output you want.

Andy.
