Ground
Connected to the Crystal oscillator. The EXTAL pin is also able to input external clocks.
(10 MHz)
Connected to the Crystal oscillator. (10 MHz)
Power supply (+5V)
When the address strobe pin is “Low”, indicates that address outputs on the address bus
are valid. (IC772)
When the read pin is “Low”, indicates that the external addresses space is in the read state.
(IC201, 751)
When the read pin is “Low”, indicates that the external addresses space is in the write
state and the data bus are valid. (IC201, 751)
