Hey Jules - a great place to start for various questions is the official
Atari 8-bit FAQ:
You should find port pinouts, PSU info, etc. for each model.
One thing you'll notice right away is that, besides the coax RF hookup,
there is also a monitor port with 5 pins. You will get better picture and
sound using the composite video and audio outputs from that port on the
>From the various vendors, I recommend a couple specifically:
With some looking and contacting, you may find a lot of things you want. Of
course, eBay will have lots of stuff. Also, check and use the marketplace
forum on AtariAge. The folks in the 8-bit forum will also provide a wealth
of knowledge for future questions.
It's possible I might have spares of some of the things you'll be looking
for, so feel free to contact me offlist if you like to go into any detail.
