Was about to test the newly modified ATX PSU in my Quicksilver G4... before I realized it was missing the CMOS battery (I forgot what Apple calls this, but it's the 1/2 AA battery that lives on the mobo... whatever).

Was about to test the newly modified ATX PSU in my Quicksilver G4... before I realized it was missing the CMOS battery (I forgot what Apple calls this, but it's the 1/2 AA battery that lives on the mobo... whatever). Why I bought a new battery for it, then realized the PSU was going to need replacing before it would work, and then removed the brand new battery I bought is a mystery to me. Maybe I thought I'd be holding onto it long enough to worry about the battery leaking a corroding the board? (iirc it was a lithium battery though, so honestly no idea what was going thru my head... or where I stored it in the meantime lmao)

Going to try anyway... I have a whole pile of 3.7v batteries from "disposable" vapes, so why the hell not?
I don't have the system drive that came with it anymore (well I do, but I repurposed it for something... I think it's currently living in my modded PS2), so I popped in a random IDE drive I had lying around, and I'm going to try booting into 9.2.2 via USB using the OS9 Boot Kit from Macintosh Repository. The last time this G4 ran, that's what I used, so assuming this does in fact work, and I haven't wired it incorrectly (I have confirmed that nothing is going anywhere that it's going to cause damage, so the worst case scenario is that a wire is missing, not something like +12V going into a +5V rail), then there's no reason I shouldn't be able to boot OS9 from USB again.

Don't judge the soldering too harshly. I only have two hands, and no good helping hands or other work holding apparatus lol. The joints are good, but there was a lot of twisting to keep things together, so everything just looks like a massive glob of solder. Those 100V diodes have pretty massive terminals that are not nearly as flexible as the wires lol
Anyway, gonna go take a shower. So if I have made some obvious terrible mistake, hopefully somebody points it out before I get back and apply power.

I almost made a very dumb mistake initially. This power supply has a second 4-pin connector that latches onto the P4, I guess for motherboards/chipsets that require 8-pin power?? I don't actually know. I bought this for a build with an LGA1150, when 2011v3 was already the new hotness, so maybe some higher end chips on that platform required it?
Anyway, I swapped the polarity on one of them, but without even thinking, I initially plugged in the other non-swapped connector. Of course that also means that the wires I cut and soldered (removing the pins without the correct tool is do-able, but also a huge PiTA, so I decided for the P4 power to just snip the wires) are going into an incorrectly keyed connector 🙄. I could've just done the same thing again to the other, but it was nothing a sharp knife couldn't correct lol. I also know from experience that the keying is easily bypassed with muscle+stupidity (a much younger me once managed to plug a 4-pin molex into an IDE drive upside down), but that feels a little too barbarian for what was for a long time, my "beige whale" (however uncharacteristically un-beige for the time period it was).

@gordoooo_z dear baby jesus, do not plug that PSU into an electrical source, unless you really want to smell burning PCB and melting wires.
which model MB is this?

Sono giunto -da molto tempo- alla conclusione che c'è moltissima gente che riesce a "ragionare" solo in senso binario: a favore oppure contro, questa tecnologia oppure quella, o di qua o di là. Capisco che serva a ridurre l'ansia e alle menti semplici ma, credetemi, così non andate da nessuna parte.

Diario di bordo – Il dominio delle frequenze 📡⚔️
Non sempre le battaglie si combattono con spade o scudi,
La missione 🎯Analisi con Kismet: mappa del caos etereo.Individuato il campo libero: il canale 6, silenzioso come una radura incontaminata.Decisione presa: bloccare lì il 2.4 GHz, stabile e ordinato.Riattivato il 5 GHz, lasciato al band steering, come cavalleria veloce e imprevedibile.
a volte si vincono scegliendo il canale giusto. 😉Obiettivo?
La prova ⚡Router in console, parametri da domare.2.4 GHz fissato sul 6, immune a interferenze di vicini rumorosi.5 GHz liberato, canali automatici, pronto a far correre chi sa volare più alto.Band steering attivato: il router come stratega invisibile che decide le mosse.
Domare il rumore, bilanciare gli eserciti, dare a ogni device la sua strada.Successo? 🎉
Morale 🧙
La rete canta più armoniosa, i pacchetti scorrono come cavalieri in parata.Ogni guerra di segnali è fatta di scelte sagge,
e a volte basta un click per trasformare il caos in armonia.SUCCESS?
Sì.
Conquista: Stabilità +1, Velocità +1. 🏅🙏

L'idea di clonare nuovamente il badge del lavoro e di metterlo nell'orologio c'è ormai da mesi, ma non ci ho ancora provato nell'orologio, dovrei ribobinare il tag #NFC

> Maori scholar, Makereti Papakura writing at her desk c.1910. The room is decorated with a mix of Maori & European mementoes whilst the rafters are painted with traditional kowhaiwhai patterns. Makereti will be awarded a posthumous degree in Oxford tomorrow, almost a century after she died in 1930.

@bbacc sono d'accordo, io riguardo ad altri periodi di crisi simili ricordo anche persone che a me pareva fingessero molto, credo anche con sé stesse.

flash back to 1999 to the childhood of a future google engineer at the precise moment she realized she accidentally installed adware on her family's computer: "wow I want to make all computers like this when I grow up"

Reitero il mio appello: adottate un #PowerMac #G5 Potete anche togliere la motherboard e mettere nel case strafico una dozzina di Arduini…Venite a prenderlo, ve ne prego!
