Good progress.

Dried, plugged in. Current consumption was ok.

Ok, fired up. It responded and erased just fine.

@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.

Reflashed with BETA1SS fw. Headers and socket added.

Then I hit the first snag. I discovered I have no free 030s

Removing them is a perilous task.

I'm not doing that again.

This will take a couple of days to fix.

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

I use a wallpaper scraper to start it off

Hopefully you will have better luck getting running than others are having.. I'm fast running out of things to fix

I like it.

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