Maybe try to trace this in MacsBug to see if it consistently dies at the same address? This could help narrow it down to bad ram.

I made progress but then got distracted by other shiny objects :) I'll pull it out this week and see where I left it. I am determined to make it happen!

Wow this is pretty cool! Nice work!

Just playing the devil's advocate.... Have you tried writing to PRAM and making sure that remains persistent? You could use a tool like PRAM Doctor and write a unique value in to some byte. Power down and walk away for a couple hours, then when you power back on make sure it is there.

Glad to hear it is working well for you! Take a look at the ROM downloads on the CayMac site. The 040 ROMs are past beta now up to v1.0. Still working on finishing the 030 version. https://ko-fi.com/caymacvintage/shop

I'm trying to find the link for what I bought for my LC475/Q605. I went for the 128MB SIMM. But importantly I think I bought the one labeled "angled socket" so it would fit correctly.

Nice! I've been on the look out to buy an SE30 as well. I used to live in Salt Lake City right across from the University of Utah. I remember back in the mid/late 90's, I would often go into their surplus store. They had a LOT of SE30s on the shelves, but at the time they just weren't of any...

OMG, I cannot wait for this PDF! Thank you so much for doing this :)

I have run into this issue with PRAM Doctor as well. Trying to remember the details, but it might have been on a PowerBook 540c perhaps? But generally for my other 030s and 040s it has worked pretty well.

PRAM Doctor is part of this combined download. You can mount this in an emulator like Basilisk then scrape out the program from there. There are three pages, and on each page you can hold down Command-Option to modify the values. Then you can "write" the value back to PRAM...

I honestly can't remember where I pulled this document from, so I cannot give credit to the source. I think I may have edited it anyway. But this has been really helpful for me. Also PRAM Doctor really is a great tool. Not only can you view ALL PRAM/xPRAM settings, but you can also directly...

Yes 100%, go with BlueSCSI v2 if you can. Makes doing stuff like this just so much easier. Then on macintoshgarden.org, you can easily get all the install media up through OS 9.2.2.

Yep one step at a time. Up to 9.1. Now moving on to 9.2.2. For no particular reason but the fun of it :)

Yes and Yes to all this @croissantking! Here it is now with 9.0.4. Taking baby steps.

I am interested in pushing this to 9.0.4 next. But can certainly say it is noticeably slow with 8.6, which isn't a surprise when considering the slow bus speeds. I think maybe what I want to see is if it would be possible to watch a YouTube video somehow on a Blackbird. I haven't actually done...
