Right now, I have a cmos 4040 counter and a 74HC393 binary counter.
There are other counters I could buy, but I won't buy them until I can see that they can simplify my design.
I'm asking for a counter, because I have discovered that my last ROM programmer failed to work 1/2 the time, and if I pick better counter(s), then maybe I won't have to make my tracks so narrow.
I want to know what counter(s) I should use. I'm dealing with a single-sided board, and I can't go too much lower than 0.6mm or I will risk breaking the track with the soldering iron. Also, I want to avoid wire jumpers as much as possible.
Basically my ROM programmer has counters interfacing to the 28C64.
Until I get a good answer, I will have to try to come up with something.
Seems that the PCB is the hardest part about the circuit, especially when I don't have professional tools.
And if audioguru thinks I make "toy" radios, wait until he sees my "toy drill" :lol:
