Data outputs are indicated by Q followed by a number. One-inverter oscillators are indicated by X0 and X1 pins, where X0 is the inverters' output and X1 is the input. If I happen not to know which is which, the pins are indicated by X1 and X2. A crystal oscillator can then be made using X0 and X1. The clock is positive-edge triggered.
Complementary outputs are available.
Yup, it was choking on the PC8 'fancy' graphics.
