Bandai RX-78 Gundam Personal Computer Joystick Pinout

The Bandai RX-78 uses a proprietary joystick port with an 8 pin din.  This din should be a 2-3-3 layout with all pins symmetrical.  It also makes use of two ground connections, Ground 1 provides Fire, Left and Up when connected to the relevant pins and Ground 2 provides Right and Down.
