@exxos - What's the most appropriate fw to flash on it?
edit - I just put
https://www.exxosforum.co.uk/atari/last ... NT30SS.zip on there. I'll solder the header pins and cpu socket tomorrow.

You need the BETA1SS firmware else you probably kill the osc or PLD.

Then I hit the first snag. I discovered I have no free 030s :? Removing them is a perilous task.

This will take a couple of days to fix.

I don't want to see that happen again. Far too much haste.

I like it. :) I'm thinking of two ways forward, but it'll be a few days. No more broken 030s, or anything PGA.
