Hey retro Mac nerds… is this what it looks like? Is Chicago making an appearance here in the wild, here in 2026? #marchintosh

Someone trashed this Bondi Blue iMac G3... can I fix it?

I am proud to present GlobalTalk Chat 1.2, taking it from a rushed #MARCHintosh hack-job to something I'd be proud to release as shareware 30 years ago!

The headline update is it now allows anyone to host their own room! And it works on any AppleTalk network, not just #GlobalTalk

Get it on BaroNet, or Macintosh Garden https://macintoshgarden.org/apps/globaltalk-chat

And for anyone who has been curious how it all works, documented source code is available! https://github.com/kalleboo/GlobalTalk-Chat

My #Marchintosh PowerMac G4 MDD is done for now. I’ve dubbed it “The Bionic Mac”. Now sports an ATX power supply, a hacked-in Radeon 9600 from a G5, SSD connected to PCI SATA, USB 2.0, and a new, quiet, pleasingly blue main fan.
If I want to get a vintage Mac or before-Mac Apple computer, which one would you recommend? #MARCHintosh

Rhubarb update, 5 May 2026.

SE/30 for scale.

Finally posted my #MARCHintosh results - https://jonschwenn.com/marchintosh-2026/

I had intended to post this a month ago, but things have been busy. I want to be more intentional about writing on my website more this year. It feels like documenting things on actual websites you run is a thing of the past and important details or knowledge is lost into the ether that is social networks or videos.

MARCHintosh 2026

My planning for this year's #MARCHintosh started on April 1st of last year. Over the last few years I've used #MARCHintosh as a milestone marker and a way to encourage me to take on new projects. I was more ambitious with some of the projects, including more soldering and ordering PCBs. I'm going to break this post down into a few sections: the prep leading up, the results, and the plans for next year.

@RonsCompVids I bumped into someone at VCFSoCal that was giving away discs that perform the unlock at boot. I also found the PCB design for the expansion port to add on a floppy. I was thinking of some interesting #GlobalTalk things I could do for #MARCHintosh 2027  

So my interest is 25% gaming 75% what else can I make this thing do

Help me, where’s the Thunderbolt 2 port?

SUCCESS! Finally got the Macintosh 512Ke on #GlobalTalk ! I couldn't find a Phone Net box with a DB9 connector, and my attempts to bodge one together weren't working. Picked up a DB9 LocalTalk connector for less than $10. Now I'm ready for next year's #MARCHintosh , or #Apriltosh , or maybe #AprilApples (though I think LocalTalk only worked on the IIgs.)
