    My New Quadra 800

    Does your drive also have the front panel (Volume/Headphone) board? I have caddy drives that have that board and others that don't, but there are caps on that board too and it's connected to the audio out circuitry of the drive...

    My New Quadra 800

    Have you recapped the cd drive? It's really mandatory to do on these...

    Mac Plus 68020 Accelerator

    I googled and found actual pictures of a Big Mac, and it's definitely not that. I should have checked that before I posted! Also I think the Plus has a 16Mhz clock anyway. It's the fact that it's soldered to the logic board and that the part numbers are in-series that leads me to think that...

    Mac Plus 68020 Accelerator

    Hold up! The part number and the silkscreen style - is that a factory fitted upgrade?? Edit: This hints at such a prototype... https://folklore.org/Evolution_of_a_classic.html

    840av nubus slot A works, but makes the system unstable...

    I have recapped and cleaned the board. The connector is in good condition. There were only a couple of broken traces on this one, none near the nubus section, cap damage on the lower half of the board was extremely minimal. I have an update too - it is only SCSI cards that are unhappy in this...

    SuperMac Thunder/24 Help?

    See my last reply - the card has rom 1.16. I've just been using it in 7.6 and the only issue I could see is that the options dialog of the Monitors control panel doesn't show any of the card options when using SuperVideo 3.1 control panel. However, older versions of the SuperVideo control panel...

    SuperMac Thunder/24 Help?

    No longer relevant in light of OP's unfortunate developments ( :( ) But for the sake of accuracy, my card has ROM version 1.16.

    SuperMac Thunder/24 Help?

    I have a Thunder/24 with older ROM 1.7.? (I'll have to look it up later) that works just fine in 7.6 and 8.1.

    840av nubus slot A works, but makes the system unstable...

    As per title, nubus slot A (the one with the inline DAV slot) works superficially, but attempting to use functions of a card installed in that slot freezes the system in pretty short order. Tested so far with three scsi cards (SEII, SEIV, Jackhammer) as those are what I have on hand. All...

    Powerbook 3400c Ethernet instability

    IME, old machines and modern switches or routers are rarely functionally reliable together. I have an old thread on here somewhere about my router causing my G4 cube to lock up after a few minutes of ethernet activity. Why your 3400 worked normally prior to the drive transplant I have no idea...

    840av with Jackhammer won't shut down

    That's awesome thanks! I will make a point to try it as soon as I have enough spare time, and let you know.

    840av with Jackhammer won't shut down

    Too up-to-date perhaps? I previously updated it to 3.2.3, and since read in the readme that 3.2.3 was specifically for compatibility with the Targa 2000. "This version is designed to fix compatibility issues between the Truevision TARGA 2000 (NuBus) card and the FWB SCSI JackHammer. If you are...

    IIci too much memory...

    I thought I knew all the key combos, but this is a new one on me. Is it confirmed, and on which models?

    840av with Jackhammer won't shut down

    ...or restart. It locks up right at the point where it would normally power down and just sits there. If there are no drives connected to the Jackhammer it works normally. If I swap out the Jackhammer for a Silicon Express IV, it works normally. Apart from the shut down issue, everything...

    MP-F75W schematics available?

    Very likely, but the pinout matches the HA13421 so the schematic is probably useful to you even if not exactly right.

    MP-F75W schematics available?

    Looks like the CXA1035 is it - U3. IC's rebranded at some point during the production lifecycle?

    NEW Injection Molded - iMac G3 Inner Bezels

    Yes, it was fine. I've no horse in this race, but I would hate to see this thread locked because of one idiot who believes he is naturally entitled to the fruits of someone else's labours and a few bandwagoneers who appear to have a chip on their shoulder about the OP. Believe me, you are far...

    NEW Injection Molded - iMac G3 Inner Bezels

    I am a manufacturing engineer by day. Plastic FDM printing is pretty much the absolute lowest quality method to manufacture anything. It's appeal is that it is cheap and easy with a very low barrier to entry and enables just about anyone to make things that they couldn't otherwise. The amount...

    Daystar PowerCache Quadra

    This is interesting. I have one of these, but as discussed here, in a 800 the difference it makes is so marginal I wasn't even sure it was working. I don't remember if I ever tried it in my 700 as that has a PowerPC card in it, but looking at your results it seems that it would be far more...
