Gregory's ServerEPSON WHY DID YOU NEED FOUR CONNECTORS FOR A TWO CONNECTOR POWER SUPPLY?

 it has been ZERO DAYS since I have had to open up a laptop just to figure out where to shove volts in yeah I've not seen this kind of RAM module before. some kind of Epsom custom thing, maybe? AH-HA! that was the wrong manual. They DID change the pinout! Thankfully, it's compatible. how long has it been since you've had to straighten the pins on your RAM chips? Because for me it's "today", but I imagine for everyone else it's either "never" or "when I tried to upgrade my IBM 5150 PC" or "I had one of those computers with ZIP RAM" yeah this RAM module uses a 44-pin (2mm pitch?) connector. That's great if you want it to be possible to accidentally plug your hard drive into your RAM slot or vice versa! Normally that's not remotely possible for so many reasons. I seriously can't think of any era of PC hardware where that was even remotely possible, for physical connector reasons. You could use the same connector for both RAM and hard drives back in the early PC era with HardCards and RAM upgrade ISA cards, but that wasn't really a case of mixing up the connectors: they just both plugged in the same generic place. THE PINOUT IS FOR THE POWER CABLE NOT THE POWER CONNECTOR ON THE LAPTOP meaning: yeah, I borrowed someone who has... nosmia? Whatever the term for "has a sense of smell" is. It's got Magic Smoke Stank now. Pulled everything out. It's a small computer! This is everything but the keyboard, hard drive, floppy drive, and screen. apparently instead of having a "POWER GOOD" pin like ATX PSUs do, they went for the opposite, where they have a pin that tells you if the power is sus *amongus noise* someday when I have money again I'm getting me an inspection microscope with HDMI out so I can do better close-up pictures of these things. Do they make smelloscopes? wait ZOOM, ENHANCE! I don't think it's supposed to look like that (Amusingly, I'm listening to Well There's Your Problem in another tab) the question is: what the fuck is this thing? the label has been sadly... exploded. I think it's either a MOSFET or a very small voltage regulator?       @foone I came here to ask if anywhere it specified which view that pin out was 😅  @foone This is why I usually connect ground to the shield of a DB connector. Still not foolproof  @foone Often! I repair old arcade game PCBs and the 2114 RAMs are a common failure point. The hoard of new old stock ones I've got needs to have their leads formed to fit in the board.  @foone That wasn't uncommon on early laptops, everyone had their own form factor. Toshiba had a different module for every blasted laptop model. Infuriating when you want to upgrade your Satellite or Libretto, even when they were new.    @foone huh! I've seen a couple SIPPs before but not in a short laptop format like that. @foone@digipres.club   @petrillic @foone That would be my guess as well. Split the current over two conductors so you can get a better per-metre price on the cable.    |
well I beeped it out and either this is a different connector, or they lied and pin 1 isn't ground, only pin 3 is.
