Q: PowerMac 7500 Hesitant Startup
My PowerMac 7500 has a really odd power up issue, and it's done this every since I owned it.. Too bad back in the 90's I never took advantage of the warranty and now am interested as to WHY it does it.
What it does, is when I press the power button, it always never boots. It comes on, but the screen remains blank and no signal. If I force a reboot, Command Control Power on the keyboard, then it boots up and proceeds to run without issue. It does occasionally freeze up bad, with no mouse cursor movement, but every classic Mac I've ever used that was PowerPC has always seemed to do that.
I do not know why it does this though, always requiring a force reboot just to turn on.. It has done this since day one of owning this brand new, literally, but was always shrugged off cause it worked otherwise.
It has now since been upgraded to a 1GHz G4, with 1GB RAM, and Mac OS 9.2.2 (through some tricks), but even with all new other components on the motherboard, it STILL does this.
So the other day, I found another 7500 logic board. I stuck it in, and well what do you know, it does the SAME thing! I'm confused now. Was this a common problem with these machines?
On a side note, where can I even find a OS 9 CD that will BOOT on this Mac? I lost my original OS 9 CD that I got for it when it first came out, but every OS 9 CD I find has 9.2.2 and won't boot on it.
It still has it's original 1GB hard drive that is SCSI, and I really want to replace the drive, but I can't until I at least have an OS to put on it.
PowerMac, Mac OS 9.2.x
