Hello!
First post here and growing retro Macintosh enthusiast.
I grabbed a IIsi from goodwill about 8 years ago for $5, took the battery out and never touched it again knowing I'd get to it eventually.
Unfortunately it seems that the top UE5 ALS245 just.. fell off due to corrosion from what would either be battery leakage / PSU leakage.
I've since taken off all the caps, cleaned the board through and through, the PSU, everything.
Unfortunately I can't find a schematic or a understanding of what the UE5 ALS245 chip or any of the ALS245 chips do.
What is the possibility of fixing? Worth fixing? Or any tricks I could do to actually ever see this thing working?
If not, I'll use it as a practice board for other projects, such as working to be better at re-cap/soldering/etc
Thanks for any input!
