Good manual. It is complete and of high quality, both text and graphics. The schematics are with the original big size, so it can be viewed or printed without any loss of resulution and sharpness.

1-2. Note in Replacing the TG Board
When replacing the TG-121 or TG-163 board with a new one, remove the PROM on the new board and replace it with the PROM that was mounted on the former TG-121 or TG-163 board. TG-121 board (B side) : IC2 TG-163 board (A side) : IC11 Note in Replacing a PROM To remove a PROM, remove its socket frame. This socket frame is so fragile. When removing the socket frame, therefore, it is recommended to use a special removing tool listed below. If it is not available, use a small slotted screwdriver or similar item as a substitute for it. To remove the socket frame by using a screwdriver, proceed as follows. IC socket removing tool: Sony part No. J-6394-110-A Socket frame: Sony part No. 1-540-194-12 Removing a socket frame (by using a screwdriver) Insert the screwdriver as shown in the figure and push it lightly in the direction of the arrow to unhook the frame socket.
