Get a B&W G3 compatible modem port to serial port adapter (g3 stealth serial port or griffin port or circuittalk) https://68kmla.org/bb/index.php?threads/introducing-and-interest-check-circuittalk-localtalk-for-powermac-g4.40182/ Then you can do MIDI like older beige Macs - externally clocked.

This is going to be difficult to debug without a built-in serial port. I modified the Forth code to include bytes 0x60 to 0x7F from the PC ROM. These bytes include the subsystem vendor id and device id (0082:0515). I don't know what the other bytes are for. I also added a property "start" that...

Open Firmware does not use semi-colon to separate commands. You have to encode the property data before you finally create the property. Like, you need to place numbers on the stack before you can use an arithmetic operator: 1 2 + . result:3 ffffffff should work. -1 is the same value. This...

I think I remember placing a penny on top of the read/write head of a Mac Plus or Mac Classic floppy drive so that it would read floppies, back when Canada had pennies.

What's the valid form of this invalid OF?

The adapter requests 28V 5A from the PD charger. If the Cube tries to use more than 5A then something might happen. The adapter or charger might detect overcurrent and stop providing power or something in the adapter or PD charger (but not the Cube) might get hot. If something gets too hot then...

Your repository is a fork that is behind the upstream fork. I made a pull request to the upstream fork (just ROMs - no resource forks).

Seems like a solution would require a lot of hacking. Maybe convert the ATY,Apollo PEF into a shared library that doesn't match against the PCI device, create a wrapper NDRV that loads and calls the ATY,Apollo PEF and logs all the calls.

There's probably zero chance you can get acceleration in Mac OS 9 since you're using a GPU meant for Mac OS X. Without the "ATY,Apollo" ndrv, Mac OS 9 should be able to use the "Non-existent hardware" ndrv from the "Mac OS ROM" file. It only requires Open Firmware to enable the graphics and set...

Try installing latest ATI drivers from https://gona.mactar.hu/ATI_Mac/ ?

You could dump the PCI info in Open Firmware using my lspci for Open Firmware script. Include output from dump-device-tree and devalias and printenv as well. https://tinkerdifferent.com/threads/erics-apple-network-server-700-tinker-log.3987/post-41227

The suggestion was to switch master and slave after getting the HD to boot. Switching the devices means the HD would not have the same boot path that allowed it to boot so then it probably won't boot. disks are weird in Open Firmware. Multiple disks of a bus may be represented by a single...

Changing the device master/slave setting changes the device's Open Firmware path.

The B&W G3 has device aliases that you can use for the boot device path: 0 > devalias pci /pci bridge /pci/@d mac-io /pci/@d/mac-io via-cuda /pci/@d/mac-io/via-cuda rtc /pci/@d/mac-io/via-cuda/rtc adb-keyboard...

A DLOG combines the info of a WIND with a DITL. Dialogs can be modeless - meaning you can interact with other stuff while it is displayed and it can be resized. Sample source code and resources at https://68kmla.org/bb/index.php?threads/localtalk-but-faster.45615/post-505648 I don't recall if...

0c:00:10 is FireWire OHCI https://admin.pci-ids.ucw.cz/read/PD/0c/00 0c:03:10 is USB OHCI https://admin.pci-ids.ucw.cz/read/PD/0c/03 OF 3.1.x has code for USB to use the keyboard but that's about it. OF 3.2.4 adds USB and FireWire mass storage support. TIL? Later definitions cannot override...

I created a 32K ROM in the Test1 folder in the attached zip. The ROM is using version 113-XXXXX-210 of the Rage Mobility Mac firmware from Open Firmware 4.6.4f1 iBook G3. It doesn't contain a Mac OS or Mac OS X driver. Those should be included in the OS. I guess the first step is to see if it...

Open Firmware in the B&W G3 is missing mass storage drivers for USB and FireWire. These can be found in later versions of Open Firmware. USB is OHCI, which should be in every version of Open Firmware that supports booting. Search for fcode images for the class code 0c:03:10 3.1.0f1 PowerBook...

The updater says it just improves PCI performance. I don't have a dump of the original firmware to compare so I don't know what changes were applied. My latest ROM list is at https://68kmla.org/bb/index.php?threads/pex-rom-project.23568/post-573923 I usually update the list at...

I've been looking at ROM checksums recently. A Power Mac ROM has 14 checksums. The first 5 are for the first 3 MB (the 68K part). The remaining 9 are for the entire 4MB ROM, including the PowerPC/Open Firmware part (the last 1 MB). Of the PEX ROM dumps I've seen, only the TriPEx.ROM is...
