Doorking 1838-010 circuit board for 1838 Phone entry system

Worked great as a direct replacement for a board damaged by lightning strike. Well packaged in foam and electrostatic foil. A few instructions would have been nice, regarding the need to add TWO chips (memory and APB) and advise that one connector can be removed to make wiring a lot easier, but the board itself worked perfectly - and shipping/packaging was fast
