Model 1 Video Mod

[Jonathan Herr]

I know from googling on the web, there's a way to get a model 1 to use
composite video output. The thing is, I don't know which pins are pins 4
and 5 on the video output on a Model 1 TRS-80, and since Ira's site doesn't
have the manuals, as well as me not being able to find my manual for the
darn thing, I'm a bit leary about randomly hooking up pins to plugs. Anyone
have a place to find the pinouts for the darn video port? I'm really eager
to try this mod out!

DIN plugs normally have the numbers in the plastic next to the solder
thingy or the pin. They are standard. When you take the plug apart and
look at the solder thingies 4 is the second on theleft side and 5 is the
4th.

1 4 2 5 3 (as seen on the solder side on a male plug)

The video o/p was 2v p-p composite video. The pinout of the jack is:

2 1 - 5vdc @ 30ma
4 o 5 4 - composite video
o o 5 - computer ground
1 o o 3 2,3 - no connection
