On Saturday's noon EDT stream, we're going to build a Monotech MOS 8501 CPU replacement to see if it will fix my Commodore Plus 4. Then we're going to to do some chill CPU pin straightening and try to repair a forgetful ASUS A7V400-MX for @trinastechnobabble https://youtube.com/live/mJa62tYHN4E?feature=share

After watching the wonderful @mac84tv video on the MIMMS iNSPIRE exhibit, I noticed this early Macintosh ii prototype.

I have to admit I got *very* excited, as this is only the second Macintosh ii prototype I've seen. (YACCintosh and the Big Mac technically don't count, as they're a different architecture)

(Thanks to Mac84 for sending me a few more photos of the exhibit!)

no one needs it, but it's cool:

an old version of the macOS flurry screensaver is open source, so a few prompts later we can have it ported to Metal and running in a tvOS app https://github.com/zadr/flurry

And here it is, the #MARCHintosh #GlobalTalk Canvas 2026 timelapse. Thank you to everyone who participated, it was lots of fun to host!
I love the Apple IIGS. It’s a great computer, but could it have been greater? The legend goes that Apple purposefully underclocked its CPU during development to avoid competing with the Macintosh. But is it actually true? Join me for a deep dive into the IIGS architecture, the life of the 65816 CPU, and the ghosts of keynotes past. https://www.youtube.com/watch?v=UDUQEKxfGEw
