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?

The DingusPPC emulator uses a Unix Domain Socket. I suppose you could pipe that to a TCP port or a TTY device or a serial port using socat. But for output to a real serial port device, you would want the emulator to use that serial port character device directly which can support serial port...

I've added your commit to my fork. I don't know if it works. Try the release: https://github.com/joevt/SlotsDump/releases/tag/v1.7 The .mcp files are CodeWarrior Pro 4 project files (CodeWarrior IDE 3.3).

It should save properly, as it would be interpreted as an entire disk. If the iso is from a CD, then the resulting .img might be suitable only as a CD. I would examine the partition map of the disk image using dumpvols.sh on macOS to see if it makes sense for a CD or HD. CDs might have block...

I'm not sure about Macintosh II. SlotsDump worked with a Macintosh LC at least. And a IIfx. When I tried them in 2004. I don't remember if they were 24 bit or 32 bit addressing. The LC had slot 0 at 00A7FFFF (ROM) and slot E at FEFFFFFE (PDS Ethernet). The IIfx had slot 0 at 4087FFFF (ROM) and...

DingusPPC has SCSI hardware emulation. It can boot Mac OS 7.1.2 to Mac OS 9.2.2 from a virtual SCSI hard disk. Whether it's proper or not depends on if it works with whatever you're trying to do. If you're writing to a SCSI hard disk, note that the disk image should be blank or have an Apple...

I wonder if any modern GPUs support Apple Sense codes? https://tinkerdifferent.com/threads/documentation-for-db15-to-vga-adapters.318/post-21288 If not, then you'll need to setup a custom timing that matches whatever is required by the display. Here's some timings at...

But there are two serial ports. AppleTalk usually uses the printer port. So the modem port should be free. What port is selected for AppleTalk? Of course, if you don't have an AppleTalk network, then AppleTalk should be turned off.

I suppose if you can't move it to a PC and use NVFlash from Windows or DOS to dump the ROM, and if there's no Mac utility to do the job (Graphiccelerator? NVUserXFlash? NVIDIAFirmwareUpdate? ATI Multi Flasher NVidia? ATI Multi Flasher NVidia.app?) then there's a couple options: - Get a dump...

Can you get a ROM dump of the card? I want to compare it with the 6800 ROM dump that I have. I also created an Old World Mac compatible version of that ROM and some other Nvidia ROMs (6200, 6600, 7800) that only worked in New World Macs. PCIe cards require a PCI to PCIe adapter for most Macs...

Asynchronous in this case just means that the sender and receiver don't share a clock? They must use the x16 or x32 or x64 clock mode to recover the clock from the receiver. They don't have a start bit or stop bits? They use a SYNC character? I'm adding logging to DingusPPC to show how the SCC...

The Hammerhead memory controller in those machines actually supports an extra 128 MiB on top of that 1.5 GiB (1.625 GiB total 0x68000000). You can try this in the DingusPPC emulator. The problem with > 1.5 GiB 0x6000000 is that the 68K emulator used for classic Mac OS versions is hard coded to...

External clock is probably the easiest and best choice: https://68kmla.org/bb/threads/localtalk-but-faster.45615/post-505309 The PCLK could be used, but there's a couple issues with that: - Different Macs have different PCLKs. Maybe only Power Macs had PCLKs in the >10MHz range. - The PCLK has...
