Very interesting, thank you all!! I'll definitely check the -12v rail, I've been meaning to open it up and reflow some of the analog board solder joints anyways. Glad to know the pops and difference in volume are normal at least! ymk: The volume control does indeed work.

I've tried to find threads about this but all I can find is people talking about the speaker being too *quiet* with regards to capacitor issues, though that is mainly on later models. I have the opposite problem with my SE though! The speaker in my Macintosh SE (non-FDHD) is uncomfortably loud...

Just wanted to report that this works perfectly on System 6 after changing the file type from scri to INIT. Thank you for making this!

Hey all! I have a Western Digital 320 GB drive which was bought new around 2010-ish. When using it with my Power Macintosh 6500, I can create a partition (without using the whole 320 GB of course, only around 128 GB shows up; I created a 60 GB partition) and install 8.6. But it then fails to...

too many computers but no motivation to do anything with them... i should pull out my iBook G4 and write some classic Mac OS programs or something

Interesting, thanks both of you! That explains why it wasn't shorting 3.3v to ground like I half expected it to.

Hey all, I have a Performa 6300CD motherboard that has been sitting in a drawer for a few years and I'd like to plug it in and play with it. I *did* previously try running it in my Power Macintosh 6500 case and it worked fine, but now that I think about it, I remember reading somewhere that...

Hi, I recently installed Mac OS X Jaguar on my iBook G3 500 MHz (dual USB). It runs alright, but the main issue I have with it is that shutting down normally (via the Apple menu) does the normal shutdown process but then doesn't spin down the hard disk before cutting power, resulting in it...

Just tried that, I wasn't able to copy the color icons directly so I just created blank/empty ICON recources with the same IDs. Still getting the same error.

It doesn't seem to be reaching that point yet, I replaced the DisposeCIcon call with ReleaseResource but I'm still getting the exact same error as the second image in my previous post. Also these errors occur when I open the control panel, not on startup, which at least makes them a bit easier...

Update on attempting to patch the color QuickDraw calls: I used ResEdit with a CODE editor addon to modify those traps to what I assume are the original monochrome equivalents. Unfortunately it now crashes somewhere else, probably because differing formats between color and monochrome icons. :(...

Oops sorry, yes the one that was crashing was PRAM Auto-Restore. Looks like the issue is because of a call to `GetCIcon`, which based on the name I assume is a color QuickDraw trap and iirc the original 68000-powered Macs don't have support for that. Now I'm curious to see if I can patch these...

I found this little application which seems to do the same thing except not automatically on startup. The source code is also included in the archive, so I might end up making my own little utility/INIT based on it: https://macintoshgarden.org/apps/pram-reader

Hmm, I just installed System 7.1 on the same Macintosh SE and I'm getting a similar unimplemented trap error, except without MacsBug since I don't have it currently installed. Outdated/incorrect ROM version maybe? I have no idea.

Update: looks like it doesn't like running on System 6.0.8, despite the readme saying it would probably be compatible :p It dumps me into MacsBug with the error "Undefined A-Trap at A0073CF6"
