    nubus scsi card any benefit?

    For those documents, install the AppleGaramond font posted at: https://68kmla.org/bb/threads/lc-developer-note.41114/post-502133 For modern macOS, open the 348KB file in Font Book.app to install the 6 type faces.

    LC Developer Note?

    For example, that font works with the MESH pdf documents at https://68kmla.org/bb/threads/nubus-scsi-card-any-benefit.200/post-590813

    From happy Mac to flashing question mark during boot?

    I don't understand why it wouldn't work in Old World if it works in New World. The only valid difference would be in Open Firmware. Do you still have the cards? I would compare .properties in each case to begin with. PCI spec differences between Old World and New World? I have a Nvidia 7800GT...

    MODTracker audio replay on early 68k macs

    I don't think MOVEP.L supports post increment addressing mode. Also, 68K assembly instructions have source as the first parameter, and destination as the second. You would probably have an unrolled loop like in the examples given in earlier posts. Do several moves in a row then an add...

    Power Mac G4 MDD and the USB 2.0 chip

    The iPod only has FireWire 400. You'll want a Hard Drive enclosure that supports FireWire 800 to test the speed of the FireWire 800 port. If you had a second Mac with FireWire 800, you could try FireWire 800 networking. Try iperf 2 for PowerPC Mac OS X? You could also try FireWire target disk...

    Macintosh LC Hardware Book Recommendations

    Service Source? Developer Note? https://www.macdat.net/repair/apple_docs.html Looks like there's no developer note pdf there. Here's some docks in Microsoft Word 4 (for Macintosh) format. I guess you can open them in Infinite Mac. There's also a PDF converted version. You might want to try...

    180MHz 603ev CPU upgrade for 5300ce?

    I would like a copy of that dump when you get around to it. Or maybe someone with a complete 5300 can do it.

    MODTracker audio replay on early 68k macs

    MPW has a powerful 68K assembler that supports macros and such. Can you link object files generated from that into Think C? I did that with Think Pascal. Attached are some projects I implemented in Think Pascal and 68K Assembly from "Zen of Graphics Programming" by Michael Abrash (First...

    Power Mac G4 MDD and the USB 2.0 chip

    That one says 3.0 instead of 3.1. It unstuffs into a .img file that is actually a MacBinary .bin file. Decoding the MacBinary gives a functional disk image complete with file type/creator and resource fork. I couldn't open the disk image in Leopard so I used DiskCopy in Mac OS 9. The disk image...

    Radeon 9100 that I can't flash

    Show the error message? Usually you don't need the name and unit address to specify a node in the device path. Either of these should also work: dev agp/ATY,R200Parent dev agp/@10 I don't think this is a rabbit hole I want to explore. You remove the other graphics card when trying the new...

    The "820-0961-A" mystery G3 3.3V FlashRom

    So the Xgecu will have a method to connect an entire DIMM? That would be useful.

    Tango 2 without drivers installed is hanging my 6360 during Happy Mac phase of boot. Does that make any sense?

    The Gazelle PCI Fix applies to the Open Firmware phase which is before the Happy Mac phase. Is Happy Mac phase before the part that lets you press the shift key to disable extensions? Check the Open Firmware phase by connecting the Power Mac 6360 to another computer via serial cable. Capture...

    Power Mac 7500-9600 Bus Speed Overclocking

    Right. The PCI pinout shows no request/grant pins. Also the PCI command register (PCI04) in PCI config space does not have a bus master bit. https://www.bitsavers.org/components/cirrusLogic/graphics/ Need to verify that the documents are referring to the same chip that is in the ANS.

    The "820-0961-A" mystery G3 3.3V FlashRom

    It depends how many address bits exist at the ROM slot and how the G3 decides between built-in ROM and ROM DIMM slot. The Beige G3 schematics is missing the page containing the built-in ROM chips? At least, I know sheet 9 is missing but that's for DRAM DIMMs. Actually, does Beige G3 have...

    Radeon 9100 that I can't flash

    Do you remove the chip to flash it with the TL866? Perhaps the problem is when you reattach the chip.

    The "820-0961-A" mystery G3 3.3V FlashRom

    It would be nice if the flash ROM had a switch to enable built-in ROM in case the flash ROM has a bug and needs to be reflashed. While in Open Firmware, the switch can be changed to expose the flash ROM for flashing. Would it be possible to have a jumper or something on the flash ROM so that it...

    Radeon 9100 that I can't flash

    That dump was bad - maybe because the TL866 had a bad connection. A copy of a bad copy is bad. Hmm. The TL866 should have been able to write the entire 128K correctly in that case. It's unclear how ATI Multi Dump would return only the last 64K unless the last address bit was mixed up. That...
