Hi,

NitrOS-9 Level One runs quite well on a 6809-equipped Atari.  I worked on the port myself, and am quite pleased with the results.  So there is no hype here -- it actually works.

I see a lot of speculation on what the Liber809 is or isn't, or what it's supposed to do for the Atari A8 platform.

To be clear: I created the Liber809 because *I* wanted to see a 6809 and NitrOS-9 run on an Atari -- nothing more.  The fact that it is a complete, salable product is lagniappe (read: bonus).  I'm not trying to push the Atari community in any particular direction, nor am I trying to prove anything with this product besides the fact that it could be one.  It was simply for my own satisfaction (and I'm quite satisfied).

There's no reason to read anything more into it than that.  If you want one, then by all means buy one.  If you don't, then that's ok too.  It was a fun project for me, I learned a lot, and I made friends in a new retro community.  That's a win for me.

Bob, that does work.  It's almost as though that particular FREDDIE has trouble in that particular XEGS system.

Another datapoint would be to try another XEGS system to see how the Liber809 worked.

Rybags, I can try that.  I still have the 6502C and ROM that I pulled, so I can do some swapping around to see if that helps.

The Liber809 board now generates phi2.  I did not try swapping the Liber809 board in the 130XE as well, but that's another datapoint I could try.

But doesn't the BASIC come up running from ROM?  If so, putting the BASIC in RAM and running it from there *might* show the problem up with the 6502C in place.

Here's one additional datapoint to add to this problem.

This morning, I put a 40 pin socket on the 130XE where I had removed the FREDDIE last night.  I then took the "bad" FREDDIE from the XEGS and put it in the 40 pin socket of the 130XE, and it boots up fine!

This is a bit mystifying.  The FREDDIE that was in the 130XE works fine in the XEGS, and the FREDDIE that failed in the XEGS works fine in the 130XE.

Just to make sure, I put the original XEGS FREDDIE in the XEGS again, and it still failed.

I ordered from these guys last week and they are awesome!

I also posted a new entry to my blog about the XEGS fiasco:  http://liber809.blogspot.com

Thanks Rybags and bob1200XL for all your help.
