Hello All,

Thanks you for your inputs. Special thanks to Sloboday
Mandaric for suggesting to use 74LS374 in place of
74LS373. The LS373 was OK but the LS374 was better. It
was a pin for pin replacement so it was a slam-dunk
choice. Also special thanks to Michael Karas for
recognizing the objective of the circuit and telling
other members who didn't have such a quick wit.

The project was labor intensive but it taught me a good
lesson which is to use what you have. It turned out
better than buying the $0.50 IC because it would have
taken about four days to arrive and would have cost
about $10. www.mouser.com was the cheapest vendor. They
sell single items but they only ship UPS which in my
case would have been about $9.00.

Below is a picture of the printed circuit board I banged
out. I installed it into my project and it came up right
away.

Thanks,

Charles Bannister
