Hi everyone....I am new here and would welcome any help to me from more clever people !

I am studying a microprocessor schematic ( which is a tall order for me lol ). But in observing the 'clock' circuit, i can not make much sense of this type D-flip-flop circuit when comparing it to others in searches. Is this a standard form of clock-circuit that would feed a PAL logic chip for memory timing to and from a Motorola 68020 cpu ? Also, if the clock speed of the cpu is 20-mhz, what should be expected at the two outputs in this flip-flop circuit ?

Regards, Bradley.

The floating input on IC1a is bad news. It's impossible to answer without fixing that.
