Repairable 800?

[Xebec]

Hey folks, I have a 3rd Atari 800 I received from someone years ago, and finally got a chance to open up and see why it wasn't working in detail.

 

I did a quick glance a few years ago, and saw the SIO port was literally broken off of the power supply board, so I ordered a new supply board.   I also did some "plug and play" testing and found the ROM and a couple of the RAM Modules weren't working in another 800 (or at least that's what my notes say), and that the brick power supply was good.  Today I finally opened up, what I saw is below.  This is already a kinda rough 800 - a few holes in the top of the case from too long screws being used in the past, a few missing keys, etc.   

 

I plan to keep this at least as a parts 800 in case I ever need in the future, but I was was wondering if something like this is even potentially fixable, as these are getting somewhat rare/special.  How many layers is the 800 PCB?

 

Note, the IC (POKEY) I took a pic of was installed with one pin 'outside', and it looks like the die in the middle tried to push upward (overheat/overvolt?)

Hi. Its 2 layers. With enough time it can be hand wired back to normal. Time is hard to find! Best of luck

Good grief, someone burned the crap out of that poor board trying to remove components.

nope, that is a combination deal 😮    Some of the those components torched, and some of that is an amateur hour comedy routine for the removal of the bad components, the hot spots on some correlate with searing component death...

And here's the original power board for this 800, I guess that's one way to remove the SIO connector?

Also, bonus damage pics of the metal shield..  This must have gotten pretty hot..

insanity!    hmmm looks like untested $2,500.00 ebay material here... you can call it possible heating prototype atari!

Did that thing get hit by lightning or something? Good freaking grief!

 

As for that poor SIO connector/power board - someone call 911. We need to report abuse of a corpse.

a crime against Atarinity!

We have to be thankful for the people at Atari to totally misjudge the need for replacement power boards or for not aligning power board and mainboard manufacturing numbers... It‘s really interesting to be able to buy a NOS component for a 40 year old design at such a ridiculously low price.

Yeah, that's not much more than what just a right-angle SIO socket costs.

Chances are Pokey survived.  I butchered an Antic chip during removal about 10 years ago which involved several legs being lost, soldered new ones on and it still works after that and probably a bit of heat stress in the process too.
