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 Outdated/incorrect ROM version maybe?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"

Oh that looks perfect! Thank you :D

Hi! So, I've been playing around with a Macintosh SE that I recently acquired and of course, the PRAM battery on the motherboard is long dead (I plan on opening up the case to remove it soon). This is mostly fine, I don't mind the fact that the date and time aren't accurate. However, what does...

Woah, this is awesome!! Just finished reading through the entire thread. I've wanted to get into retro Macintosh programming for a long time but I've always struggled with finding the motivation to learn how the Toolbox works, it's so different than what I'm used to :P

CodeWarrior doesn't seem to support assembling bare assembly programs, at least not that I've found. (If it is actually possible, someone please let me know how!) I've been using Macintosh Programmer's Workshop, which gets the job done but it has a bit of a learning curve.

After taking a break from this for a while I decided to give this another try, and guess what!! It was the simplest fix, ti works perfectly now. This was the fix, however I had to keep the `QDGlobals` definition outside of MAIN for some reason. The final code looks like this: include...

I'm not quite sure honestly, it's hard to tell. I would assume the power supply fan would be the louder one since it's larger.

I recently got a Power Macintosh 6500 and after playing around with it for a little bit, I could've sworn I heard the fans ramp up and down every now and then. But as far as I know, these older generations of Power Macs don't support variable fan speeds, right? The reason I'm curious about this...
