 +  * The 'TH' line is used as the photo diode input for the Light Phaser.
 +  * This pad uses a pinout similar to many others.  There is a comparison of MSX, Sega, Atari and other connectors [[sega_atari_MSX_x68000|on this page]].

 +Tiny numbers can be found on most DB9 connectors; they're small but they're there.  Be careful not to wire things backwards!
