I would still try and get to the bottom of the "gets hot" thing. Intermittent failures can be caused by voltage dips which can be caused by a faulty regulator and/or accompanying capacitors.

I'm also self hosting Snipe-It, but with an attached Python script to generate labels/tags in three different sizes. It's a lot of work, but once you get in the hundreds of parts it's a necessity. I recently found a stack of third gen Ryzen CPUs that I fixed the pins on before using an inventory and …

Thank you everyone! Doesn't sound like it would replace my ET4000, but a solid buy for 8€ nonetheless. Neat!

Bought this ISA GPU for 8€ without further research, solely because of 1MB VRAM and the shiny sticker. The internet is inconclusive about how useful it is. Any input?

You could take one of the others off and check the capacity - I suppose the voltage rating won't grossly exceed the CPU supply voltage, so I'd just take one with a package that fits and is at least at 6.3V or something like that.

Well, I got a bit further with my PT-432B. Today my shiny new XGecu T48 arrived and I was able to look into the BIOS chip. Turns out it was completely blank, as in FF all around. Wrote the only available BIOS from RetroWeb on it and it verified just fine. So I have a board that tries to post now: …

Well, the most thorough fix would be to replace the socket. Some repair shops are equipped to do this, but it may cost more than the Mainboard is worth right now. It's something that could be done at home and the socket + expendable material would come in at about 5€, but there's a lot of equipment …

Do you know what brand of motherboard is that? Rather unusual design with cache chips on the lower right corner. It's a Pine Technology PT-432B . It hasn't arrived yet so I can't verify the sellers claim. Apparently the (formerly leaking?) Battery has been replaced with a hacked in coin cell, so it …

Single cell charging circuitries are pretty much always the same: depending on the battery type there is a voltage cutoff, regardless of the capacity. So in theory the new battery would charge with the same current as the old battery, thus taking longer for a full charge, it should fully charge …
