Its my understanding, after reading all kinds of electronic and non-electronic
info about the 520 and 1040ST, that:

- Initially, the 520ST had an analog RGB and non-standard hi-res B&W video out
- Future (and current) 520STs have a composite video out and an RF modulated
  video output.
- The 1040ST has only the analog RGB and non-standard B&W video out

I have also read one comment that seems to indicate that the 1040ST has
composite video on some pin, but not brought out to a video jack.

QUESTIONS:

1) What resolution modes can be displayed through the composite video out?
2) What resolution modes can be displayed through the RF Modulated output?
3) Is there really composite video on some pin of some connector on the 1040ST?
4) Since I must have composite out for my application, what is the difference
(besides cosmetic) between a 520ST upgraded to 1 Meg & 2 DS Drives versus a
1040ST with a DS external drive?  Will they both run the hard disk?

Thanks muchly.
