[Coco] Gal Logic

[peak at mail.polarcomm.com]

Does anyone know how to program a coco type clock generator 
into a GAL chip? I understand combinational logic fairly 
well, and am able to use "boolean" logic equations. My 
understanding of "clocked" OR "Registered" logic is a bit 
rusty.
What I want do do is build a dual J-K flip flop E and Q clock 
generator in a GAL device not in TTL!
Also is there a library somewhere of equations for flipflops 
etc?
