I just picked up a Mac SE/30 for $100. Let's pop it open and see what horrors await inside. I'll also do a little recap (get it?) of the fun of VCF East including my table collapse! Thursday (10th) at 4:00PM eastern (I won't have a Saturday stream this week). #vintagemac https://youtube.com/live/L8UoYkGAqEc?feature=share
I need a way to extract files from DiskCopy 6 images. If I could convert to raw or DC4.2 that would work, or just extract the files. There seems to be no way to do this.
I don't want to but I could script and fire up an emulator to convert them, which would take way too much time as I'm processing 100k files.
Also yes I'm handling resources as apple double format.
Anyone know what the CRT refresh rate on the original Mac / Fat Mac / Mac Plus is? 60Hz?
It's time for a #MARCHintosh retrospective!
Firstly: I've attached a photo of the remaining gifts to the drop box that have come in since the 15th!
Secondly: I've completed a final pass-over of the servers on #GlobalTalk, left my calling card, and a print job for anyone who hasn't had one yet (as long as they have open file shares/printers). Results of that are attached as well.
Finally, the retrospective itself:
It's been an absolutely CRAZY month:
- On Day 1, my SE came home from the workshop with a fully-serviced floppy drive and '030 accelerator...
- ...which I didn't even end up playing with at all, because on Day 2 I bought a Power Mac 6500 for an absolute steal (and I STILL have to explore the other external HD that came with it)
- GlobalTalk completely dominated the month just like it did last year. I rebuilt my QEMU VM for running AIR a couple nights before the start of the month and it's been absolutely rock solid stable ever since.
- I made great progress on my project for the month, archiving my collection of Mac floppies from the early 90's. I'm only about 40% done, so this will continue into April as "bonus content" 
- No updates on #Macstodon - but I did verify that it works perfectly fine on Mastodon 4.3 if you manually authenticate by copying the URL to a modern machine, and copying the auth token back to your Mac.
Lastly I want to give thanks to everyone in the #VintageMac #RetroComputing community for making this such a fun event every year! I love seeing all the greetings showing up in my drop box, and to my printer (which is now off for the year - but the PDF printer is available year round!) But I especially want to thank the following folks:
- @kalleboo for TalkCrawler and for putting together an amazing GlobalTalk scavenger hunt!
- @europlus for his hard work on the AIR Administrator's Manual Addendum and VM images for QEMU!
- @scj for the GlobalTalk updater app!
- @theirongiant for 68K Radio, which has been my background music while working on my vintage Macs this month!
- @polpo for creating the ImageScribbler card which made it possible to send print jobs to so many more people this year!
- @dmark for maintaining netatalk, making it possible to share files over AppleTalk directly from my NAS instead of having to keep an old Mac running all the time!
- @DrJosh9000 for jrouter, which I'm looking forward to trying again now that the month is over and I can start messing around with my setup - it's had a lot of bugfixes and updates!
- @_the_cloud and @jimluther , for sharing great knowledge from their time at Apple with the community (and for helping me troubleshoot some crashes)!
- @RonsCompVids , @MuseumJoe , and @mac84tv for putting together the annual MARCHintosh event!
Until next year!

TAM alert! Someone needs to buy this, get it working, and connect it to #GlobalTalk before #MARCHintosh ends! #VintageApple #VintageMac #RetroMac #RetroComputing https://shopgoodwill.com/item/225304640
“Apple’s long-lost hidden recovery partition from 1994 has been found”
This is a fascinating deep-dive into a classic recovery partition that existed nearly twenty years before Apple stopped shipping physical install media. Originally seen on r/VintageApple #VintageApple #VintageMac #RetroMac #RetroComputing #MARCHintosh https://www.downtowndougbrown.com/2025/03/apples-long-lost-hidden-recovery-partition-from-1994-has-been-found/
So, here's my actually-planned-for-this-year #MARCHintosh project. Attached is a photo of four very dusty containers full of floppy disks. These are the actual disks from my childhood IIfx!
Most of these disks aren't original. The originals lived at Dad's workplace. He would periodically bring home software from work, make a copy of the disks, and return the originals to work. These were, I'm told, the "off-site backups", in case there was a fire at the workplace or something like that. But we also had all this software installed on the family IIfx so Dad could read any files that he brought home from work with him.
Of course, we also bought our own software for the home, and those are mixed in with these disks as well. And that stack of CD-ROMs in the top left are my MacAddict cover disks - those are already archived.
Anyway, because these are just consumer-grade diskettes, they degrade quicker than the professionally-manufactured original ones. I've already lost a few, so I want to get these archived! And of course, anything that doesn't already exist on the Garden will be uploaded there and shared on #GlobalTalk as well.
(expect this to be a long-ass foone-style thread with lots of updates over several days)
Tried out InterPrint on my IIfx today and I've got to say, it works beautifully!
https://macintoshgarden.org/apps/interprint-112
This Chooser extension allows you to print to LPR queues over TCP/IP. But unlike the IP printing support in LaserWriter 8 (which "requires" Mac OS 8, though I think you can manually install it on as low as System 7.5.3), InterPrint works all the way down to System 6.0.5! It fully supports PostScript, too.
What this means for me is that after #MARCHintosh is over, I can repurpose my Raspberry Pi, which currently acts as an AppleTalk print server for my local network (and #GlobalTalk, by extension).
The year is 1991, it was either a car or Macintosh PowerBook, so here’s me taking the metro with the latter.
(Haha, new #MARCHintosh acquisition! PowerBook 145B, with an internement display, TBD, but it was $50, very pristine and en canadien français).
My first 68k PowerBook!
Any #VintageMac collectors (or not-so-vintage Mac folks) in the Seattle area who would be interested in some older/slightly older macs for free before they end up in eWaste? Ping @Nshrubs as she is trying to clear a bunch of stuff out of her house.
This was a fun quick procasti-project. It's double-sided too (it's a blinking question mark after all)!
I don't have a multi-filament printer so I implemented a satisfying snapidy-snap system to print the distinct black and white colours (but there's also a file in there if your printer can do multi-colour!)
It can also be a luggage tag, or keychain, or just a fidget token (it's got a nice heft to it)
New #MARCHintosh fashion!
For when you need to show the world you haven't booted yet.

Does anyone know how to swap the Command and Option keys on Mac OS 8.6?
I tried following the instructions from here: https://macintoshgarden.org/forum/how-swap-cmd-and-option-windows-keyboards-classic-mac-os (which worked for me on System 7.1), but they had no effect on Mac OS 8.6.
I even tried modifying the other KMAP resources (and substituting their IDs in ROv#) but that had no effect either.
It’s alive! Sort of. All I can do for now is look because I can’t find the OTG USB hub I ordered to go with it.

The new Power Mac 6500, "Miracle" has been moved onto the Tower of Power
The internal hard drive is truly dead - Apple System Profiler is the only thing that is able to see it. So I connected the 4 GB LaCie SCSI drive up and formatted that to use for now, until I can pop in a new internal drive or a CF to IDE adapter.
There's still a weird problem with the video. Sometimes when I boot the machine, there's no video at all, and I have to power it off and back on again a few times before the video returns. But when it does have a picture, it's stable, and not flickering like it did on the TV or the monitor that it came with.
Finding an install disc to boot this from is troublesome. Most of my classic Mac OS install discs I burned 25 years ago, and turns out they don't work properly any more and just make the CD drive spin up and down a lot (like the 8.6 disc in the attached pic).
Eventually I found the original Mac OS 8.1 install disc from my Dad's old G3, which works, so I'm going to install that for now and see if I can upgrade the OS either to 8.6 or 9.1 later, once I have the machine on the network and can install from there.
Back to the Duo Dock logic board "Gemini" logic board PSU connector pin out. I found a couple of sources.
1st, a picture of the PSU connector to the logic board showing the wire colors.
2nd, a forum post where someone troubleshoots a PSU.
I've confirmed the GND, +5V, and +12V pins correctly (SCSI power) but I can't be sure of the others.
What do white, yellow, brown, and light blue wires typically do in an Apple PSU of that era?
