You are reading my notes correct. AFTER I had shorted (Or assuming I had).....
.........."I then went back to IC48 Pins 1/2 and sure enough it was back to its initial state, however this time I was able to read the frequency at 200KHz. (This was a clean Square Wave with the Highs and Lows of equal duration)"
I am going to keep hunting. I personally feel that IC48 is still a working unit. Unfortunately, I will never know if that little slip has made things worse, or we are just seeing the intermittent behavior of the fault.
No hurry, I know you have a life. This is a huge project and honestly its giving me a headache. However I am not ready to give up yet.
Cheers
Steve
