Are you measuring under load or with a loose unit? The PSU can only be measured reliably under load

I was more impressed that you managed to squeeze in 7.5 on a rom :), I’ve always used 7.1 with enabler since it takes up a lot less space.

This helping? https://bus-error.nokturnal.pl/article2-Incorporating-m68k-assembly-code-GNU-GAS-in-GCC-C-C-programs

Some stupid questions: *You have changed the MMU tables to map up 8MB? *Romdisk located at 40900000? (40880000 at 512kb ROMs) *Romdisk size <7MB (maximum 6.99MB, this is different from IIsi where you can use the whole 8MB, on 1MB ROMs there must be a few bytes to spare) *Driver numbering...

The only other changes are modifications to the mmu table to allocate 8MB for the rom and address stripping for the 24bit mode. Only ”necessary” changes are the changes to the MMU tables. All this is only to be able to support rom disk in 24bit mode. If you don’t want/need rom disk, you can...

LOL, yeah a true laptop :D

So, just back my IIfx logic board from @WillJac and it looks ABSOLUTELY FANTASTIC!!! Some background, some years ago I bought a IIfx which had one battery destroyed. I was able to get it somewhat booting, but over the years it got from "ok" to "works with quirks" to "no longer working", so I...

The issue is finding a PC case that is screwed together... All I have found so far are riveted together. No issue since one could drill out the rivets and make a new back plane, but would be nice with something that actually is screwed together instead. I've seen some rack cases that are, but no...

Unfortunately not a single screw would line up, so I made an ATX-dummy board where I then made holes to mount the Q900. But that was actually great since it made it possible to get all connectors out of the case in a nice way. Only issue is of course that I can't use the Nubus, but since I'm...

lol, yeah, that't not gonna happen on a 900, it caps at 37Mhz due to limitations in the graphics circuits. But a 475 board might be another story ;)

For my extremly silly build of putting an Q900 in a modern ATX case I'm using water cooler from Cooler master with a custom bracket :D :

@zigzagjoe has done some fantastic work here you might also be interested in :) https://github.com/ZigZagJoe/Mac-StorageCard-DeclROM

@Hollie fantastic writeup! This thing is absolutely awesome!!

Wouldn't the PDS be 20Mhz? Since that is what the IIsi stock is running :). Awesome work as always!!

Since @derek asked in the first post about Meanwell-powered-LC, I just want to say that I created one and it's now available: https://ko-fi.com/s/561c04e288

Have you replaced UB1? Startup is one circuit and shut down is another. I had same issues as you (also one battery bombed) and had to replace UB1 and also repair some vias in that area.

Nothing you can buy outright, but they are easy to crimp. I might have a spare one

The G3 has a special pinning and the biggest difference is that it a 3.3V machine. So ROM for those are completely different.

Should be possible to build an adapter and actually use the current programmer. So far my main issue has been sourcing that a lot connector for the PPC ROM.

Weird issue, Can you try another OS, say 7.1? I have Bolle and carrera also, but runs without those issues in my machines. But I almost exclusively run 7.1 on them. Did you patch the OS also? Maybe you can try this image...
