Greetings - well I figured with all the extra time right now from being home, I would attack my portable backlit model -
Removed all the caps, cleaned all the gunk with IPA< recapped -
New 6V battery and new 9V battery -
Powers right now, nice bright backlit screen, but it will not boot from floppy, or hard drive which I assume the hard drive is just dead - but the floppy - oh boy -
I tried another floppy from another non-backlit model - won't load any floppies, system 7 etc - just gives a floppy icon with an X through it - then I discovered I actually have a BMOW floppy emu!
Hooked that up and got excited for a minute when the happy face icon appeared, only to be quickly replaced by, yep, you guessed it, floppy icon with an X through it - tried many different images System 6, System 7 - etc -
from what I can gather it is more than likely the SWIM chip? Is there anything I can do to test this? I have another backlit board, but it's missing a few chips, a couple voltage regulators, etc and I don't really want to spend the time recapping another board right now, that took longer than I was hoping, and I'm very bummed that its not up and running now - any and all help would be greatly appreciated -
Thomas
