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

Yes, broken gear, the small gear is made from a softer material than the rest, and is driven directly by the metal gear from the motor. easy to repair really.

Yes, i agree, probably one from a Plus will work too

I agree with mikes-macs, hopefully you can get it working again, but I have had no luck so far with mines, and they were less damaged. The Mac SE is far more reliable, and can be repaired far more easily.

Yes you are right, both parts of the head should not be disassembled. The head has been probably lifted and is not coming back in contact with the disk anymore. On the back of the head, you have a small spring, you can try moving the spring around to clamp it closer, but it's hit or miss.

With a Macintosh SE

Are you sure the drive’s head is not dirty ? Using « olds » disk is not ideal, as many are contaminated, and once the head is dirty, the drive will not be able to read a good disk. Cleaning the head in between is not a bad idea.

If your disk is ejected, probably an issue with the System Software, or the disk itself. how have you created the disk ? you are dealing with a 400k disk drive, so are you using a 800k disk and only one side of it ? you cannot use any 1.44 Mb disk. so in the end you will need a 800k drive to...

I have a wireless mouse, never seen any other before, working great, using two batteries in the receiver side.

On one of your first pictures, near the video connector, i can see dull pins on the 343S0161 chip legs and this one is : 343S0161GazelleVideo clock generator, LC 475/575, Quadra 605 Can you remove the chip, clean underneath and solder it back ? not saying it's your problem here but worth a...

Ni siqiuera se lo que es un cinescopio ? la pantalla ? Si eso es, lo mejor es encontrar un modelo identico o similar, mide 9 pulgadas. no pienso que nadie pueda repararlo
