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.)
So a couple of weeks ago I made a joke about what comes after #MARCHintosh and suggested maybe #SGIpril I was only half kidding.

Belated #MARCHintosh project #1 completed (mostly): I made a CatMac SE!

The motherboard is my spare/parts SE board - I cannibalized the ROM chips a while back to swap with my other SE in order to use a SuperDrive, so this one's got the original ROMs in it. It's also missing a battery and a speaker. But otherwise, the electronic bits all work great. I'm using the PicoPSU and SE-Combo board that I purchased from Joe's Computer Museum a couple months ago.

The case itself is a 7/10 for me. It's decent, but flimsy in places. That's not so much a problem with the model itself as what I used to print it - basic & matte PLA on a Bambu X1C. I'd probably use PETG if I were to do it again. Removing the supports from inside the drive slots was an absolute nightmare, even when using a dedicated support filament. And when I close it up, the BlueSCSI SD card slot is a bit askew, so right now I have to have the cover off to insert/remove the SD card - going to see if I can use a wad of tape or paper to adjust the positioning.

But other than those relatively minor complaints, it's a beautiful design reminiscent of the Apple's 80's frogdesign aesthetic. I opted for a black case, blue LED & translucent light pipe and red reset/interrupt buttons to give a bit of a retro-futuristic touch (and it'll match my Amiga 500’s new case). And it's completely quiet, just like my IIfx.

So I think what I'm going to do is swap out the motherboard with the one from my other SE, so this one will get the recapped board with the 030 accelerator on it. I'll move the floppy drive over to this machine as well, and then it'll move over to my Tower of Power. Since the BlueSCSI V2 on this machine also supports Wifi, it means I can put away the Asante EN/SC and save even more space (and power outlets) on the Tower.

As for the other SE, I think I'll give the case a good cleaning and then move it to my living room where it will become a "working" display piece (like my 30's Minerva radio).

Was checking my router config for unrelated reasons when I went over to the bandwidth monitor tab and remembered it splits out AURP usage.

For the month of #MARCHintosh, my network uploaded nearly 300 *mega bytes* of data to #GlobalTalk !

Quick little goodbye and see you next year for #marchintosh #globaltalk
