That output appears to be good. Only complaint is your input command line was truncated at 80 columns width, but I think that's ok since everything else was not truncated. One improvement might be to do setenv fcode-debug? true and restart before doing the commands. But it appears that...

I would have to compare the Part1.txt and Part2.of files of 4.1.9f1 and 4.7.1f1 to find all the differences, which you probably don't care about, such as adding support for vectors , 16-bit fcode numbers, booting from sata, etc. It's just Open Firmware stuff that mostly has nothing to do with OS...

Newer Macs with modem port to serial port adapter can use AppleTalk (LocalTalk). For example, a B&W G3 with Griffin gPort or similar adapter. https://68kmla.org/bb/threads/introducing-and-interest-check-circuittalk-localtalk-for-powermac-g4.40182/ http://alexhixon.com/jamport/index.html

I have a 4.7.1f1 firmware updater that might work with your iMac. It's the latest 32-bit firmware updater that I have. It has config blocks for 66 different Mac models. Your iMac has prod-id:0x0081.00 which is renamed from "Kihei" to "P7". Versions of the firmware updater since 4.5.5d2 have...

This is an iMac so the GPU is probably the original. Grab the iMac firmware from Mac OS X and we can compare to make sure the firmware updater flashed it correctly. It's probably fine since it has checksums.

One way to tell if you did it right is to open the file that you created and compare its contents to what you saw when you did the command. In this case, it seems that only part of the output was saved. You need to increase the terminal scroll back buffer in your Linux app. In macOS, I use...

"iMac Firmware Patched" is the firmware updater. If you open it in a text editor, you see that it starts with some Open Firmware code. \ Copyright: (c) 1998-2001 by Apple Computer, Inc., all rights reserved. \ 000419F1 20010914 hex device-end 0 to my-self The first line is an Open Firmware...

Yes, that's the ratio. The document you posted makes this pretty clear. My suggestion would be to convert that document into a utility (a bash or perl script or Hex Fiend.app template) that parses the config block in order to understand your config block. The config block starts at 0x3F00, as...

Thread title says 9700. But your post doesn't say 9700 anywhere. It mentions these: 6700, 9500, 9600. I wonder if some of those are mistyped. 6700 is a pizza box form factor of the 9700? Or is that a form factor you are choosing for your PEx case design? Does your PEx boot? Which ROMs are you...

Anything is possible if you throw enough code and electronics at it. Using the Macintosh Portable video output was discussed at: https://68kmla.org/bb/threads/macintosh-portable-video-adapter.32038/ Here's an Apple Macintosh Portable Video Adapter M0251 description...

I didn't say you could not read the Apple Partition Map. I said that you cannot read from the Apple Partition Map and from the next partition in the same command. Below is output from my fork of DingusPPC. MetaImgFile lets you construct a virtual disk comprised of multiple disk images by...

That's an Infinite Mac error message. It's not from Snow. That's a bug for @mihai to fix. I think device header means the part of the virtual SCSI HD that is not the HFS or HFS+ partition? i.e. the Apple Partition Map which is generated programatically if a disk image does not contain an Apple...

There's this: https://github.com/hanshuebner/maciifxsimm I haven't tried it.

Does Symantec projects not have a concept of multiple targets? Might be time to upgrade to Metrowerks. You can set that up to build everything with a single key press using multiple targets and dependencies. You can look at the Metrowerks code resource examples and see how they might translate...

List of GPU upgrades for the Beige G3: https://everymac.com/upgrade_cards/by_system/powermac_g3.html The two most interesting seem to be these: PowerForce G3 ZIF 1.1 Encore G4 1.0/1M

You said this which implies there may be a lot of tests (like a couple rectangles per key), but I reread your post, and see that earlier you said that what rectangle to invert is figured out mathematically, which probably means you do the divide method already to minimize the number of tests so...

1) CODE resources are completely different than other types of code resources such as DRVR, CDEF, WDEF, etc. CODE resources are segments of an application. You split an application into segments to improve memory utilization. i.e. A code segment is not loaded unless code in that segment is to...

Looks like Mini vMac and Snow both emulate a graphics controller in slot 9 for a Mac II in Infinite Mac. The problem with my SlotsGrab and SlotsDump on 24-bit Macs is that the Slot Manager returns addresses in the 16 MiB ranges (e.g. 0xF9000000). Translating that address to the 1 MiB range...

I'll need to do some debugging in Mini vMac or MAME or Snow (whatever can expose the problem).

PCI vendor / device IDs? PCI Option ROM dump?
