(or let my finger decide)
The Fickle Finger of Fate?
I was messing with an arithmetic circuit (16x16 multiplier - Logic Devices LMU18) that uses a clock and I wanted to use it as a straight combinatorial circuit. So once everything was wired up it was all working but nothing to trigger the rising edge that causes the multiplication. What to do? I soldered a wire to that pin and touching it triggered the multiplication. There is your fickle finger of clock fate. Not a smart idea, right? Fortunately I didn't fry it. I wired a 555 to produce a 1Khz signal to that pin and now it produces a 16x16 multiplication 1000 times a second, running at about 1/28,000th of its worst-case rated speed. Whoot.
