I won’t repeat what stepleton said very valuable advise. I just won’t recommend to use a Mac to dump the 3.5 inch floppies (the small ones if you are not familiar with the sizes). There is specialized hardware able to dump the magnetic flow and then replay it or extract a disk image from it...

Bonjour Stephane, The damage is not too bad but will need quite some work, I know few close people on Paris that have already repaired multiple Lisa if you need, I myself would love help too, I’m based in Lyon. Most important thing is preserving the software it will ensure the computer will...

I provided scans of the 7100 ROM DIMM in the ANS Mac ROM thread, it actually only lacks wiring for the programming signals. I haven’t try yet to wire them to the edge connector, I think the flash programmer software might work. Anyway the main problem is the inital flashing. My approch has a...

Hi, Seems like those are UNC #2-56 3/8-inch. I’ll post when I will be able to fully confirm, I should receive replacement parts soon.

Driver problem, it crashes the Finder, opengl support is broken. But basic video works. Maybe related to improperly flashed card, it was a PC card I modded with a bigger rom chip.

Salut @feeef ! Since you are french beware of the ATI drivers updates since file names are localized if you use an english release on a french Mac OS install they will be duplicates and conflicts. I myself never was able to make my flashed 7000 work on my 9500 so I don’t have a step by step...

I’m afraid there is nothing special about booting MacOS it just boots like any other Power Mac: grey screen, happy mac and so on. Open Firmware stuff was related to improper configuration. Front LCD screen is disabled so nothing to see here too. As far as building a ROM DIMM, I won’t be able to...

Some news: - Mac OS 7.6 for CHRP won’t be it just freeze on the « Welcome to Mac OS » screen, probably need some modding - After patching an Si3112 card, I did boot the ANS from a fresh install of 9.0.4 of an SSD drive. - The 604 at 133MHz with no L2 cache is so slow that the SSD doesn’t make...

I think I booted my ANS of an SSD. Somehow I had the compatible hardware for this?! Where did the Murphy’s law go?

AIX and Mac OS are big-endian systems, the PCI interface is little-endian and accounted for, but I guess not for the way the video memory is dealt through the video chip thus requiring the driver to swap to little-endian. Extended RAS has to do with memory signals but I don’t know about those...

I forced the boot into Mac OS with setenv boot-command bye Now the ANS just boot like a normal Mac. To boot AIX I suspect you only have to press Command-Option-O-F and type boot to start AIX. I tried to install a video card but it wasn't detected, maybe a bad contact or a non-working card as...

Have yet to figure that out, but the 2.0 failed to boot my AIX install when I installed the new DIMM, I may need to reset the nvram. Unfortunatly my AIX install is on a scsi2sd, and my MacOS on a ZuluSCSI, I need to migrate the image because my ANS is missing a lot of accessories and I can’t...

I’ll try to look into it next time I remove the logic board from the ANS. I successfully installed Mac OS 9.0.4 on the internal SCSI bus, it’s quite slow as my ANS is only a 133MHz with no L2 cache. Video card supports 640x480, 800x600 and 1024x768 in 256 colors or gray mode only, no surprise...

@Byrd Here is a webpage that slice a 4MB ROM file in the 4 required chunks. Just open it in a browser et choose a ROM file, it will download the 4 files. Processing is done locally. I can't take a picture of the bodge wiring yet but you need to connect pin #43 and #44 to pin #23 on each chip...

Greetings, Almost a month ago @John Tucker revealed he had an ANS booting Mac OS, somehow a rumor came true. With the help of some folks at Tinker Different, 4 ROM were finally dumped and released by @joevt on his GitHub along some precious analysis. The ROM we are looking for in order to boot...
