Replacing chip reference U2 on the analog board with this: https://www.mouser.com/ProductDetail/595-SN74LS38N should do the trick I'm having the same problem and everything says to do this Even the dead mac scrolls

also, is the mouse connector supposed to be missing a pin in the corner?

No, but the screen is extremely bright so I doubt that's a problem

What's the battery for on the back of the Plus? Looks like an energizer battery from the 80s or 90s but i don't think it leaked I ordered a torx screwdriver for the handle, it should arrive soon Edit: it chimes, but shows that zigzag line pattern

I'm actually not at home right now but later today I can take off the cover of the LC III drive and send a photo. I think mine was from around September 1993 if that helps.

Alright makes sense. I actually don't have the case, board, HDD, etc., for the LC III - just the floppy drive and power supply. Do the manual and auto inject ones look different on the inside?

Does anyone know if the Mac LC III floppy drive is the same 800k drive as the one in the Plus? Or is it a 1.44mb or something? I don't know much about floppies. It looks like a very healthy drive so I was wondering if I could swap it once I have the Plus.

Thanks so much for all the feedback - I'll definitely buy this, even if I can't get it working it sounds like it's worth it with the keyboard, mouse, startup disk, and external drive.

Do you think that that's the main problem?

Also, what's with the lines pattern? Could that indicate a bad ROM getting past POST and being unable to function properly and boot? Or something else?

I feel like you're contradicting yourself here - are you saying I should buy it or not buy it? :D

What people here know how to burn new ROMs? The seller didn't check the voltages but would low voltages indicate a bad PSU that needs to be recapped or replaced? So it's worth it?

I can get a Mac Plus, Keyboard, Mouse, and a Jasmine DirectDrive 20 for $80, but the Mac Plus doesn't boot according to the seller. Should I buy it, and is the problem easy to fix? This is what the seller said about the Mac: I heard that errors beginning in 01 are ROM errors. could that be a...

I'll probably do that. I just found out about this: picorc.com I think that would work too right?
