I have decided to scrap every thing. For some reason, I just really dont care about the Stella lite anymore. I apologize for causing all of the stir up and "controversy." Bassicly, what you do, is take an Atari flashback 2, add a cardridge port via the pin outs provided on the mother board. then you take the pokect TV specifed in Ben Hecks Atari section in his book, and modify it to be back lit by LEDS instead of the back light bulb. Then you build a standard controller, also specified in ben heck's book. Here is the hard part. I could never really figure out a way to connect the controler to the pin outs of the FB2. Measuer or find out the voltage consumption of the unit, then sauter a voltage regulator to the pin outs of the desauterd power cord. Add batteries. Then connect the screen via the video pin outs on the FB2, and the pokect TV. Do the same thing with audio. then boom, you got the guts. Now mind you, it has never been tested, so do not count on it working.
Once again, I apologize for the stir ups, and I hope I havent upset you guys to badly. Besides, I've never desinged a portable before. So I suggest to leave it to the pros like ben. Bottom line, I was way over my head, I had a lot of work, i was lazy, and I'm just an ameture.
