Welcome to the A1000 owner club :banana:
Yes you've got a colour composite output.
Sadly you live in the USA, so your chance to get a TV set with RGB imput is close to ZERO.
You can hack a A520 modulator to get a Svideo output (which is a tidy bit better than the original composite output), but you can hack your TV Set and put a RGB entrance ! Go for the last one !!!
Here they have it natively since 1980, and 60 Hz compatibility since 1988...
A few moderns LCD/Plasma set can do the trick with the passive "VGA Commodore Adapter" (beware it won't double the frenquency at 31.5 !!!). Take a look at the forum about it.
