Thanks everyone, up and running with the new HDD and caps. Will do some "burn in" to make sure everything is ok before cleaning it up and putting it back together. Kids will be happy to draw(in color!) and play some color Oregon Trail tonight :)

Phase 2 - Mystic time!

I got a 575 motherboard on a trade recently so I've started prepping. My todos are:

  • Recap the 575 board
  • 3d Print & Paint bracket
  • Recap Analog board
  • 640x480 mod

I've already started with the Recap and Brackets.

Got the 3d model for the bracket from powercc (which I think came from the 3d print thread here) - ~7 hour print and looks good. Need to figure out some paint matching or maybe I'll just paint it apple rainbow colors:

The motherboard was quite corroded, some of the caps came off just with a slight touch. Took a few times to get the layers of goo to come off but all pads look ok. Still needs 1/2 more cleanings mostly around the IC's

I have a 7.1 install with System Enabler 065 v1.1 - but am not getting a "bong" or anything on the screen. What I've done so far.

Cleaned and recapped the board.

Made a battery pack out of 3 AAA batteries

Soft power is working - I hear things spin up, but nothing on the screen.

Reflowed caps just to be sure and tested continuity on the ones i could - fine.

Rescrubbed the board.

Checked voltage on the scsi port while the machine was "on" - a bit under but only by 0.25v - analog board caps are on their way but not sure if that would prevent a boot.

Disconnected the HDD to lower draw but no change.

I do see green corrosion from between a few IC packages.

Any thoughts on what else to check/test/etc while I wait for the analog board caps?
