Doh! You're quite right, Dan! What I did was use a couple of unused
logic gates to buffer and bring out a one second output pulse on the
external power BNC; essentially used the 59309 as a divider as well as a
clock. How memory fades and takes on a completely differing picture....
Thanks for the correction!
