Motorola's MC6809 was available in both clocking varieties - The 'E' suffix part number was the one with the external clock generator and two quadrature clock input pins (called E and Q). The non-'E' suffix part number had one clock input pin (EXTAL) and divided by four internally. E and Q were outputs in this case. A pin (MRDY) was available to freeze the divide by four counter to insert wait states.
It had an 8 bit ALU. 16 bit operations took two cycles, and the 8 x 8 multiply took 8 cycles.
I vaguely recall wire wrapping one of these as a hobby project in the early to mid '80s.
