    Unknown "Schlumberger" expansion card - any ideas what it is?

    Too many categories

    The way i see it, the forum is only 12 days old, officially. Yes, there are some empty categories so far, but give it time :)

    My PowerMac 7100/80 AV Recap Project

    That's not even the electrolyte, that's the solder mask that's become black because of the electrolyte, it's seeped underneath and eaten it from beneath.

    Favorite music style when cooking and when eating/drinking?

    I have that on a lot while i work....or cook. Rarely have anything on while eating though, my wife & i prefer to chat :)

    Maxell fun!

    Yep its missing the BBU and the SCC looks toast. I can send you a spare BBU, but the SCC you can buy new. It may also require you to get a Reloaded SE board, if the trace and pad damage is as severe as i think it is.

    Power Macintosh G4 - 733

    I'm imagining you opening up a trench coat and going "pssst, you wanna zip drive? It's totally legit, promise..." 🤣

    Sonnet Crescendo G4-400MHz

    Oh it's more than likely that it's crispy concrete by now, but sonnet make their heatsink screws out of alloy cheese -_-

    Thinking about it, the BBU does have issues wth two chip 1MB SIMM's - i seem to recall i knew why, but i can't place the reason why...

    Power Macintosh G4 - 733

    I've seen a few heatsinks like this - mostly on the DA and Quicksilver models. I can take more detailed pics later this weekend, as it is though, i've got a buggered wrist that's not making things easy! The countertops are a lie - veneer over chipboard ;)

    Power Macintosh G4 - 733

    Excuse the sink full of washing up! This arrived a week ago but I've not even had a chance to unbox it! I'd like to get a dual cpu upgrade for this, or should I install my Sonnet Encore ST/1800 that I scored off @Bolle a few months ago? I do also have a Radeon 9600XT from a G5, and a Geforce...

    Finally, a nice Quadra 840AV

    Check the startup circuit in order: RED, YELLOW, ORANGE, BLUE, DARK GREEN, LUMINOUS GREEN have you got continuity and the correct resistances? BTW U12 looks suspect to me. The full part number is 343S0120 - it's a 5v Regulator IC made by Sony. Available from Exshine and UTSource.

    Sonnet Crescendo G4-400MHz

    Bought for a bargain, from US eBay - sold as not working - seller stated it wouldn't boot into the OS, or froze. I have an inkling that it's either the correct extension not being loaded, or there's an issue with the cache. The cache sits on the rear of the card and it looks like a QFP that's...

    Soldering temperature

    Depends on the solder and the gauge of it - i use Kester 0.4mm 63/37 and 350 to 360 degrees is fine, although if a chunky ground plane is involved, then i just set the station to YES.

    @Branchus had an issue that turned out to be faulty ADB - that might cover some of the symptoms you're experiencing.

    Best table wine value you've found recently?

    I don't usually drink wine at all. Despite spending 12 years living in France, I couldn't stand the stuff. Even now, I find it hard to drink, only on very special occasions and I have to be in the right mood. However, on a spur of the moment, while I was about to start making Jordanian sumac...

    Period-accurate benchmarking tools?

    I would definitely recommend Macbench 4.0, as this was the last version to support 68K, but also supports PPC. Link on Macintosh Garden: https://macintoshgarden.org/apps/macbench-40

    Macintosh connector part numbers

    For the x100 PDS slot - this really does look like it'd work: https://www.mouser.co.uk/ProductDetail/587-302-182-520-900 Have a look at the datasheet: https://www.mouser.co.uk/datasheet/2/123/3/English_302_Ordering_Guide-2301523.pdf pinout is identical.
