@ClassicHasClass @joevt @Rairii Is this the data you were looking for the Windows NT register dump?
VENEER is loaded at:
image_base = 00050000
The exception occurs almost immediately:
SRR0 = 00050014
SRR1 = 00001071
LR = 00050004
DAR = 18A2D8C5
DSISR = 42000000

Sorry for the explanation not lining up, but what you replied with was exactly what I was trying to say.
I've been able to simplify the process. After 1st boot or initial install, it will boot fine just like you said. AFTER that first boot:
1. PRAM Battery removed before I even started this...
As of 1:30 CDT I was able to boot my 700 on Mac OS 7.5.3!!!!
@ClassicHasClass I've been messing around with the restarts. As of now like you said it will auto boot to a black screen but Mac OS is running in the background. I've been able to mess around enough where I think I can get it to boot...
Thank you so much for the detailed explanation @ClassicHasClass
Can you help with the quoted part above? I'm all ready to test and now understand the black screen will happen on each new boot. But if I reset the pram will it work then? You mention run boot variables but I am confused how to do...
The work being done here is incredible!!! Thank you so much @trag for making these and @ClassicHasClass for the very very detailed testing! Plus @mizerable for additional testing.
The fact that we have come this far already is amazing. Yes both current rom sims have pluses and minuses, but...
agreed. even wiping it the only stuff that "should" have been written over was the os area. The blocks should have been marked as erased but the info should be still there until it is actually written over.
Things happen, who knows if anything was even on the drive. It is still fun to see this...
We DID find a macOS rom from John. We are all trying to work together to find a way to get it to work for others who don't have the rom. I could be a programable flashed rom chip or @joevt is working on a boot loader type of idea. The experts working on this will see a breakthrough. Right now...
Sorry not sure why that link is not working try this https://juicycrumb.com/product/isp-simm/?v=0b3b97fa6688
Thanks @ClassicHasClass I was really hoping to have it ready for my VCFMW display later this year. That still leaves us some time :)
Wonderful! Thank you @joevt. I just spoke to zigzagjoe about his original product https://juicycrumb.com/store/?v=0b3b97fa6688 and if it could be one day modified for an ANS ROM. But that seems to be way too much work.
I just finished recapping a Performa 550 board that would not boot before. After a cap replacement the board booted right up. The only problem is the left side of the screen is distorted and eventually has other blue color distortion across the icons when it is booted up.
The video distortion...
