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

@chockenberry #MARCHintosh is year round, didn't you know?

Source: Me - I helped invent the thing. :D

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.
