I'd say the CPU crashed. Start with removing circuit boards and looking over them with a magnifying glass - look for "cold" solder joints (cracked) and reflow them with a soldering iron, a little flux, and some fresh solder to repair them.

Without doing anything, and after powering off and on again, does everything seem okay?

Lol. No surprise there. It never is. Too bad you got nailed on such a good game.

I'd pull the boards and check the solder joints. If all is okay you might have RAM or permanent storage issues. Wouldn't hurt to put in a fresh set of batteries too.

I have a set fresh out of the box. Protective plastic still in place.

Hey all, just curious what everyone's opinion is on the built-in diagnostics with system11, and of course Earthshakers.

I've written test ROMs for Williams system 3 through 7 (https://pincoder.ca). I picked up a working Earthshakers a few months ago but have not had time to go through the diagnostics and see what, if anything, they lack.

So before I tackle writing new diagnostics for system 11 I thought I would see what things you DO like, and what areas you think they lack or could have done better.

Thanks for you feedback

Thanks @slochar! That's good to hear (I love writing these tests).

I had deleted the post you responded to, as I was going to post the question in a new thread.. which I'll still do. Just got sidetracked.

I'm hoping that I wrote the Pincoder ROMs in such a way that they'll port easily to other hardware. 3-6 was nice because nothing really changed in those systems. 6a was easy once I had 7 done. Was hoping to do 9 before 11 but Earthshakers came across my path first.

Looks good so far! Have you got a pic of the backglass?

Nice work!
