Yes about the mouse, was just about to say the same.

Yes, I agree, probably that or worse, heads stuck in the platters. Remove the cover and have a look, probably a chance to revive the drive.

I agree

The capacitors pads are ok, but the the sound chip ones are damaged, or missing altogether.

This is the kind of protection that is present in the fuse section of any PSU

Well, i think you have got your answer, never seen a Classic working fine without a lot of work first. By far it's the most unreliable Macintosh ever built.

Yes, can be the 74LS253 (a multiplexer) legs are a bit dark in my opinion

Fault code starting with 02 is a memory issue i agree, maybe a missing trace or broken one (a bridge also can be a cause)

Can be a 1N40xx series diode ? 1N4008 or 1N4148 fairly common diodes.

Any USB will work fine to install the Operating System.... why try anything harder ?

Not an Apple IIgs guy myself, but yes the ROM 3 has a battery in a socket, where the previous was soldered.

A stuck reset line ?

Most of them are Maxell, don't say others can't go bad, but not as nasty as those ones. Had a LC not so long ago for dirtcheap (20 €) for a complete machine, including the monitor, mouse and keyboard, knowing probably the board was bad. except for the PSU, everything was Maxell bombed, Rom...

Let us know if you were able to repair it. I had 0 luck with mines, and most of the time the Analog Board and peripherals are also contaminated by the acid from the battery, so the HD and drive are all bad (more or less)

Can you just try using Dos ? Copy / B Highrom.bin + Lowrom.Bin HighLowrom.bin
