Did some research on the TS1000's composite video issue - discovered that some composite mods will overdrive the output a bit, causing the washed out image.

The solution was to drop an additional resistor in-line between the composite mod board and the RCA jack. I used a 47Ω resistor since that was a value I had handy, and it worked!

@Nathaniellockhart Thanks! Been having fun with this project. Had one of these as my first computer back in the day, but I traded up to a VIC-20. It's been nice to have access to one again to play with.

@virtualoak I tinkered a bit with one I got from a big pick up about a month ago. The pure economy of those machines, especially for the time, is astounding.
