Oh, I see you updated your post. Look for the "KDC-A04" DPST switch..

Which one, the power supply switch, or the case switch? Just search for "at power switch dpst" on google or ebay. There are tons available.

I wouldn't buy counterfeit or poor quality capacitors off Alibaba/Aliexpress.. instead purchase from Mouser or Digikey since they use trusted supply lines for real OEM parts.

haha. The hydro-dip film goes on like paint, so it can scratch. I put clear coat on it for protection.

I use epoxy. Clamp/tape the piece together so the crack is as tight as can be. Then put some metal screen mesh on the back side where the crack is, mix the two part epoxy, and spread it over the screen with a popsicle stick. It dries very fast. Alternatively, you can use the baking soda and super …

I know, I just didn't want to risk accidentally shorting pins on such a rare card.

Pinouts are different on the chips. You'd have to mod it to work. ( https://electronics.stackexchange.com/questions/57857/replacing-27c256-with-28c256-how-to-wire-we ) But the EEPROM board enables flashing on the computer itself if you put on the enable jumper. But yes, you could flash the chip …

You have to run the XT-IDE tool in DOS to configure the custom bin file, then dump it for burning, or just burn it using the EEPROM card itself.
Re: Mini ISA ROM Card

Thanks. What I had planned on doing was use the EEPROM card in a system to flash XT-IDE, and if that works, dump the pre-configured bin file to be flashed onto an EPROM for testing the other card.

They document everything really well with the scientific analysis. I'm sure if you dig in their archives, you'll find the answer. But yea, heresy.

Well, I don't know what to tell you, because adding flux to aid in removal is per IPC-7711B/7721B and corresponding J-STD-001, used by the global rework industry as the gold standard. It does aid in removal to a significant degree, and it is obvious once you do it. It clears the vacuumed holes much …
Re: Decapping techniques?

I don't know of any reason why flux should be needed when desoldering, it inhibits the job while providing no advantages to offset this. It aids in the removal so solder doesn't get stuck in tight tolerance areas. (helps it get sucked out easier) It isn't inhibiting the job at all, it makes it far …
