HOT TAKE: if you design a laptop with a power supply that looks like this, you should go to jail.

@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.
-
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.

@luana unfortunately, I live in The Past, where such things are yet to be invented.
-
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:
1. it's mirrored
2. I may have just reverse-volted it and let the magic smoke out -
yeah, I borrowed someone who has... nosmia? Whatever the term for "has a sense of smell" is. It's got Magic Smoke Stank now.
-
@foone it's going to be a deep, neurotic joy when you find out only 2 of those pins are actually being used
-
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*
-
@vga256 IT WAS
-
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.
But here's the power supply board. Something on here smells (supposedly) like Magic Smoke.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)

@foone why does this look like you edited this in ms paint?

@Aurelianite probably because Epson made it in MS Paint
-
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 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.
-
@ieure awesome. we can be "not remotely like the mainstream" buddies!
-
@foone unless its usbC
-
@RueNahcMohr god if I had a 486 Laptop that was powered by USB-C, I'd be the coolest kid in school

Here's the CPU.
Cx486SLC2.
This is a 50mhz (25mhz bus) "486" (it's a 386 design: 16bit bus, despite being a 32bit chip), with one entire kilobyte of L1 cache. No FPU, but it can use an external FPU. Performance is reportedly shit, but it's low-power so perfect for a laptop.Intel sued Cyrix over this thing. They lost.
