Connector housings and pins to keep on hand

Keep a 20 pin .156" housing and Trifurcon crimp pins for rectifier board J3 on pre-Xenon games, since it often burns; .156" pins also serve the display, sound and solenoid driver boards. Keep .100" crimp pins for the MPU and solenoid driver, plus a 25 pin .100" housing for driver board J3 if it still has an IDC connector.
