Great news! I can imagine your satisfaction. 8-)

You know. I had forgotten, but this thread reminded me that my very first Atari was a 600XL :)

Thank you 😁 Although this isn't the one I actually owned, the 600xl was also my first Atari, so has special memories. It's nice to have resurrected this one, and of course I really appreciate your input too.

I know!

This thread was in danger of becoming another Mega ST sized affair.

:dizzy:

Well done :cheer: :cheer: :cheer: :cheer:

Glad you have sorted that one at last.

Kudos

As seems to often happen, I get great ideas from folks on the forum, that lead to thoughts about what I can do next that are then applied late at night!

Still work to do to to get it to where I want it to be, but feeling pretty pleased it's running.

Thank you 😁

Big thanks to everyone who's helped on here, I couldn't do it without your ideas 😁

Ok, so have done a few iterations of the SuperSalt cart testing and we are looking fine and dandy.

Nearly all my carts work, the exceptions being SIDE3 and Star Raiders II, which I think both need more than 16K of RAM.

So, I guess I'd better try and get the 64k expansion working :)

Good luck! :-)

At least you have a known good base to start from.

Indeed. It is in theory a simple upgrade, but given my experiences here, perhaps not so much.

Do we get a pic of it working? :)
