Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.

Received a quick response, material was exactly what it was supposed to be. The service did everything I expected it to do. would use service again.

Gate array
GND
When VDD is applied from power supply IC SC371015FU to gate array µPD65005GC-556Open (Pin 26) (Pin 25) MON
3B6, gate array will send "L" signal to active the main switch signal from terminal SWO. Also, gate array will send "H" signal to release the INT0 terminal of CPU from LSO terminal. The terminal CSB is for the chip select of gate array. This signal is sent from CPU terminal CS2. And when the VDD is applied to CPU, CPU will send "H" signal to CSB terminal.

POWER ON SWITCH
When the main switch is set to on position, SW terminal of CPU becomes "L", then CPU will send "L" signal to KAC terminal to enable the system power on. The KI0 terminal is "H" when VDD is applied to CPU. Therefore, when pressing the power on switch, CPU will generate a clock pulse (2 MHz) for start up the system.
