Hi,

Have a look at the 74HCT40103 on the Philips site. Although
the output is asymmetric, it will divide by any number between 2
and 255.

Thanks for the suggestion, I've used CMOS for almost 30 years and only
use TTL when it is no other solution, one such device is with the 7493
as OH3LWR mention (believe it could divided by some strange factor,
too). problem is that I have hundreds of standard CMOS devices and
they usually (except Philips devices) goes near 10MHz. The reason for
choosing a down counter is to avoid asymmetrical output signal which
might upset the counter if the oscillatorboard has some distance from
the old dividers, but is still some 7490's left in the chain.
