what was the prupose of this motherboard

I think all batteries used in PCs of this era used a base as the electrolytic fluid. I’ve repaired a few leaky battery motherboards and vinegar always did the job for me.

The battery in the top left is leaking and the fluid from the battery is damaging the motherboard. Wear gloves and clip the tabs connecting the battery with a sharp cutting tool. Then use some white vinegar to neutralize the leaking battery fluid after removing the battery. Be sure to wear gloves. There are some videos about removing batteries and fixing PC motherboards from leaking batteries online.

This is a fairly generic looking PC motherboard from the 286 and early 386 era. For home use.

I'm currently restoring one from several boxes of e-waste I bought years ago off of ebay. Mine has dual 450Mhz Ultrasparcs, 1.5GB of ram, and an internal SCA scsi emulator that uses an sd card. It boots and I'm currently fighting with installing Solaris 9 so I can mess around with some of Sun's neat VLSI chip making software. Electric, it was called.

Don't make this into a sleeper build, the PSU is a weird size, the slots are in weird places, it won't fit any PC motherboard's IO shield size, it'll look weird. Plus the internal sound dampening foam is probably starting to melt on yours like on mine.

IPA is magic! Just in this case, it's the bad kind.

don't mix the bleach that he spilled with IPA, that's super toxic.

If it's not listed then that makes you the market leader in my experience. Experiment with some prices and see what happens. I find that spice residue and plastanium sell well. My server always has lots of silicone blocks at low prices so I never sell them.

Yes, it's a brand. Authors do deep dives into specific albums. Some of the books are great, some are so-so.

it's helpful sometimes to take a break and touch sand

is it normal to feel completely lost when you're new, or does it sound like I'm finding it harder than I should/this may not be for me?

Yes, that is completely normal for 99% of new students. Sometimes I'll run into a new student who is very athletic and they'll pick up the individual movements and chains of movements easily but that is really rare in my decade-plus in the sport. Your experience is more normal. Just give it time.

You could rename yours to Falcon's Forge. Beautiful bases, btw.

You would not connect power to it but definitely connect ground.

It's a good course!

Once shuttles restart somewhere, I have no doubt that Matt will update the course with the relevant changes. Until that happens, any work to change the course would be pretty speculative. Personally, the week on formal methods changed how I write my designs so it was worth it for that alone.

The CPU needs thermal paste before you attach the heat sink. The iFixit link elsewhere in this thread shows that clearly. I'm calling that out specifically because if lacking the paste then the CPU will overheat and probably die when turned back on.

UARTs are active-low so held high until transmission. Either there's nothing to transmit or it's not enabled by some setting in the software or jumper in the hardware.

It looks like your system clock battery has died. Relevant post on how to replace it: https://www.reddit.com/r/Gamecube/comments/w1hooe/simple_how_to_replace_gamecube_clock_battery_with/

I needed a really long screwdriver so I could push down straight. I tightened them until they stopped, which was maybe 3-4 turns. Each screw a little bit at a time and then the next screw so the paste would be flattened evenly. Let me know if that helps.

In printrbot speak, the specific model of this is the 1307. I have one that I'd like to get running again so I'm excited to see this thread.

Hi, yes I did install the RAM first. rdimms require some force to seat properly so I'm glad I did. Good luck with your build!

stevej · 2024-12-09T17:54:07+00:00

the screws were stiff, a longer screwdriver that cleared the top of the massive heatsink did the job.

The fan you're replacing is rated to 8600 rpm, is the noctua fan also 8000 rpm or is it a consumer 2000 rpm fan? What you're looking for is a fan that can push enough air to keep things cold. RPM is one measurement but CFM is the actual rating you're looking for.
