Quadra 610 Shutdown from Generic 7.5.3

Odd thing. I've just got a dead Quadra 610 booting after various repairs. I won't lie, I had some trouble with it - possibly onboard RAM, and ADB, SCSI and other things I fixed before powering it on. Mostly because of some cap rot and a couple of bent pins on the IOSB.

Something strange I'm seeing. Obviously these don't have soft power, but if I boot from a 7.5.3 or 7.5.5 CD (no System Enabler required from 7.5 onwards), it freezes when I select shutdown or restart.

Note, if I boot from a CD with 7.6.1 or newer, it shuts down and restarts perfectly.

No, I don't have a hard disk "in it", because "it" is a PCB sat on top of some antistatic bubblewrap next to a powersupply. 😆

Yep, saw the other thread. Saw that same trick in a YouTube video, good job getting this one going. I wouldn’t have shown quite THIS much persistence.

Third dead machine running in two weeks :)

Getting through some of the backlog. IIci, IIcx and a 610 so far. Probably have a go at the 7100 next. Need to review my previous attempt.

Could there possibly be something that 7.5.x is trying to run or do that is not working that is causing the freeze?

I had a similar issue with my 3400c, would start to shut down then freeze under Mac OS 8.5. It turned out to be a patched Apple CD ROM extension at fault.

I thought that perhaps I needed a System Enabler but I don't. I'm still wondering if there are System components missing from the System files on those CDs? Something that only goes in on a 610 install?

I guess the question is "if anyone has a Quadra 610, does it restart correctly if you boot the TechTool 3.0.6 CD in 7.5.5 (hold down 1 while it starts booting (before and through the happy mac stage)).

I can't put my finger on where I saw it atm... but I've seen reference to System Enabler 040 v1.1 being needed in some scenarios. YMMV

If it shuts down OK under 7.6, agree with folks above that this is probably a software issue.

Also, agree with folks above that you've done a nice job bringing that machine back!

Supporting the CD Driver idea, curiously, B1-7.5.3-R2 works fine when booted from a... erm... SCA80 18GB hard disk ;)

That's a very... uh... creative naming job for your various partitions... 🙃

Whatever works, I guess...
