Thank you. That is exactly what I needed. I had
somewhat forgotten just how slow these early CMOS devices were.
I had a 16-meg can oscillator on hand which I connected directly
to a CD4040 counter and it did absolutely nothing at all. I then
took the B section of a 7493 and divided the oscillator down to 2
MHZ. The CD4040 only worked when fed the 2 MHZ signal so I hope
the CD4048 is not slower than that or I will have erratic
operation. I will soon find out.:-) Many thanks.
