    Power Macintosh 7200 MB hi-res photos

    @MrFahrenheit The most important criteria for me is the ability to read component markings. iPhone cameras, especially in the latest models, are known to produce high-res photos. Would you mind giving it a try?

    Power Macintosh 7200 MB hi-res photos

    Hi crews, does anyone have high-resolution pictures (3000 px and higher) of the Power Macintosh 7200 motherboard ready to share? I'm thinking about providing annotated photos for various Power Macintosh logic boards. Annotations should help to identify various (AS)ICs as well as the existing...

    Monitor identification over the built-in video port on Beige G3

    TL;DR Did someone who owns a Beige G3 managed to connect a DDC capable monitor to the built-in video card? Long story: I'm currently writing an emulator for the onboard video (ATI Rage Pro) meant to be integrated in the new PowerPC Macintosh emulator called DingusPPC. While analyzing the way...

    REQUEST: Beige G3 logic board pictures

    Hello everyone, I'm currently working on a Power Macintosh emulation project called DingusPPC. Our current goal is to create a virtual software model of the Gossamer HW, that is, an emulator of the Power Macintosh G3. I need high-resolution pictures of the Beige G3 logic board (Desktop or...

    Mac OS hibernation in PowerBook/iBook

    Hello crews, I hope to find someone here who has a working PowerBook/iBook G3/G4 running Mac OS 9.x and who could help me with the hibernation feature in pre-OS X Mac OS. Mac OS 9 does support system hibernation like OS X does ("Safe Sleep"). It seems to work on laptops only - I wasn't able to...

    CUDA, EGRET, HC6805 Hacking

    Hi crews, I've just started uploading a commented assembly for the Cuda Firmware v2.37, see this Github repository. To my knowledge, that's the latest firmware available but we need to re-check it. In the next days, I'm going to put even more docs on Cuda - so stay tuned!

    LC TDK PSU issues

    Is it correct that this TDK PSU is more than 20 years old? If so, getting another old unit doesn't guarantee it won't fail, too...

    LC TDK PSU issues

    Well, if you can get a replacement PSU of the same type for little money, go ahead! If not, it's worth trying to fix the existing one as I did with my old Astec PSU (still working after been fixed). BTW, a quick ebay search reveals a used TDK 699-0153 for 79,95 € + shipping from Germany to...

    LC TDK PSU issues

    The badcaps forum (what a funny name :beige: ) has a board dedicated to PSU troubleshooting and repair. You could ask there if they can identify that mysterious component. There are several people around there skilled in the art...

    CUDA, EGRET, HC6805 Hacking

    Never heard anything about it. Can you supply some more information on that CUDA Lite chip? Well, CUDA as well as its predecessors (Bit-bang, Egret) is basically a multipurpose MCU that emulates some peripheral bus protocol using the bit banging approach. In other words, all required...

    CUDA, EGRET, HC6805 Hacking

    Glad to know, thanks! IIUC, I'd need an extra account to access the Wiki, right? Is there any ASIC-related Wiki section there? I didn't see any. Where may I post such information to?

    Q700 ADB or board kaput? Mouse clicks but no movement

    Frankly spoken, I'm out of my depth now. I think you need to gather more data on the failure of your Quadra board. Can you do some electrical analysis of your board and compare the signals it generates with a known working board? That would be very helpful. Otherwise, we won't be able to go a...

    Free 68k (dis)assembler for Mac?

    Thank you for pointing me to FDisasm that I'm aware of. I personally never considered to give it a try because I don't use Mini vMac emulator I never seen any ROM formatting files for the ROMs of my interest (PowerMacintosh 6100 and newer) MAME/MESS offered me anything I need in just one...

    Q700 ADB or board kaput? Mouse clicks but no movement

    This would be possible if your board had EEPROM or Flash storage. It's a well-known fact that all Apple desktops in the 90s use 3.6V lithium batteries to maintain non-volatile memory. That means that PRAM (NVRAM) is actually a small amount of CMOS RAM powered either by the mains or the battery...

    Free 68k (dis)assembler for Mac?

    If you're going to gather some knowledge about a specific ROM or ROMs, the question is if the static analysis (i.e. disassembly/hex dump) would be the right tool for the job. You can surely run a disassembler over your ROM dumps. The problem is that the most disassemblers are just dumb tools...

    Q700 ADB or board kaput? Mouse clicks but no movement

    Yes, I agree. Mouse movements involve interrupt signals. That's indeed smth you want to check next...

    Q700 ADB or board kaput? Mouse clicks but no movement

    I don't think it's possible. It's true that the ADB as a single-line bus requires precise time slices. But this leads to the following logical conclusion: if this timing is somehow broken, the whole ADB communication will become broken. Any partial failure can only happen after the ADB...
