#marchintosh — Public Fediverse posts

@slaine - Haha totally fair!

Hey if I may ask while I have you. What do you mostly use your Q700 for? I like to do old photo editing, word processing, games and proxy web browsing. Also very excited to have this ready for #Marchintosh next year. What are your favorite apps and games? Cheers!

What type of cable would the Apple Scribe printer use to connect to an old Mac's mini-din 9 modem port? Regular 25-pin serial? Null modem? Something entirely different? 🖨️ #MARCHintosh #RetroComputing #RetroApple #EverySinglePrinterIsExtremelyCursed

Simple Spooler 0.3 can be found on #GlobalTalk in the Cloudbusting zone, at Puppet Head:Ken's Stuff:Simple Spooler 0.3.

I've also put the source on AmendHub (thanks @jcs !) Amend is a nifty source code control system for classic Mac OS. https://amendhub.com/thecloud/SimpleSpooler

Exhibit A: a page printed on the ImageWriter II from the Service Source stack. Notice the top bar with header and page number are mangled, because the driver included superfluous commands to reverse the feed direction twice. The paper actually rolled backward, then forward again, in the middle of a line.

Exhibit B: same print job, but with the reverse feeds stripped out by Simple Spooler 0.3.

I thought I'd try to be clever and pull out the ancient Airport base station to get AppleTalk to work in QEMU over wifi. But no. TCP works just fine, but no AppleTalk. Wired only. Whomp-whomp. #marchintosh

@dmark During #MARCHintosh, @theirongiant and I were debugging AURP packet flows and found that @bytex64 had already written a Wireshark plugin for AURP packet dissection, which we used with great success: https://github.com/bytex64/aurp-dissector. It would be cool if AURP support could also be incorporated into Wireshark itself. Does NJRoadfan know about it?

Back in March, when everyone was excited about old Macintoshes, I mentioned to someone that I had drawn this icon. It's meant to be a likeness of Andrea Palladio, the influential 16th-century Italian architect. Since I didn't have a picture of him at the time, I imagined what a craftsman with a hat and ruffed collar might look like. This became the application icon for "Palladio", a grad school project which started a long journey for me. Here's the story.

#MARCHintosh #architecture

@_the_cloud @billgoats @WillFlux according to netatalk docs, "A userland AppleTalk network stack is considered feasible and is known to have been prototyped, but no complete implementation is known to the netatalk project at the time of writing."

in case anyone is looking for a #MARCHintosh project... 😅

Next #MARCHintosh people won’t complain my node is slow. 😂 Ethernet, baby! Cutting edge technology here. #GlobalTalk #retroApple

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

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.

@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 :apple_old_logo:

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

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.)

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

I probably should have asked this during #marchintosh, but let’s say I have a Mac SE and I wanted to get access to wikipedia. How would one do that? I’m okay downloading a local copy to a file server, doing whatever up-front conversions are helpful.

#MARCHintosh is over, but I've still got one more! After Be, Inc. was gone, BeOS didn’t just vanish. Leaked Dano builds, BeOS 5 PE Max, yellowTAB’s legally murky Zeta, and finally Haiku’s clean-room rebuild made for a surprisingly rich afterlife #RetroComputing #VintageComputing https://youtu.be/pS6SNa1AIWc

Not great timing with #MARCHintosh having just ended, but I finally have the time and ability to work on restoring my 512k Mac.

(Go back in this thread to see what has happened so far.)

I’m going to replace all the capacitors on the analog board. First up is the blown RIFA:

So now that #MARCHintosh is over, I spent the day doing some network reconfiguration.

Can folks still see and connect to my #GlobalTalk shared volumes? Any performance improvement?

I've switched from the QEMU VM running AIR in Mac System 7.1, over to a modern Debian Linux VM running the LToUDP fork of jrouter.

It was a bit of a pain to get everything going again - what finally made everything work was sticking to a VM on my Mac Mini instead of trying to run it all on the Pi or my NAS. There's junk that gets appended to the end of my AppleTalk packets when they cross over my Wifi bridges, and so the routing needs to happen behind one of them in order for everything to work correctly.

I'm not committing to this new setup yet, but I'll probably leave it running for a week or so and see how stable things are compared to the previous AIR setup.

Anyway, now that I have LToUDP working, it means I can access GlobalTalk volumes from my laptop without the need for a Wifi bridge (or a separate laptop), as long as I'm using Mini vMac or Snow.

MOAR ANIMATION!

Sad that I just barely missed #Marchintosh with these ;)

Is there a definitive answer to “what is the latest model Mac that can run Apple Internet Router 3?” for connecting to #globaltalk ?

What are the given dependencies that we know about? MacTCP vs Open Transport, what Max. OS version, 68K vs PPC.

Now that #MARCHintosh is over I want to do some experimenting. This also coincides with my new resolution to not use emulation for anything. Really hardware and back in the day software.
