For the 14mhz signal, I tried CDAC* XOR 7mhz and (NOT) CDAC* XOR 7mhz with a 74Fast86. The leads fron agnus to the 86 are about two inches long, solid wire. The leads from the 86 to the 68k are about 2 inches long also, with ferrite bead. Now when I turn on the computer, it ALWAYS comes up dark grey first, then bright green replaces it. I get 10 short flashes, and one long flash, and it tries to restart. I am under the impression that DTACK will hold off weird bus cycles. What is the problem here, will somebody explain why this is going bad and how I might get it to work with some extra logic? In my opinion, this is a very very poor Hack.
