So, so good.
Took a swing at buying a refurbished ThinkPad. I’m a bit undecided so far, but the keyboard hurt my brain for a second or two.

This Dell System 310 was one of my employer’s first PCs. It was found in a closet, but I was disappointed to discover the original 386DX-25MHz motherboard had been replaced with an AMD K6.

Amazingly, my long-standing eBay alert finally paid off, and I now have the system’s original motherboard!

My after-Christmas project was restoring a bunch of Macintosh IIsi. I’ve been documenting my progress at https://tinkerdifferent.com/threads/mac-iisi-repairathon.4923/

Today, the last issues was addressed, and I now have five fully functional Mac IIsi logic boards and two battery bombed units that provided needs parts.

I’ve pondered how to remove pins from power connectors, and I’ve wondered what these strange tweezer were for.

Today is the day I figured out what one has to do with the other.

Another Maxell Massacre.

A good reminder of why we GET THE BATTERIES OUT.

Verifying my rebuilt Mac IIsi with the impressive recreation TechStep diagnostic tool.

So far, the hardest part by far is removing the old connector from the corrosion-damaged IIsi PSU.
Going to build some new Macintosh IIsi power supplies today thanks to the design from @caymacvintage.bsky.social

Amazingly, the one I thought least likely to work (from a badly battery bombed Mac IIsi) is working! (somewhat)

Two out of the six I tried spun their rust and were accessible.
