Second #MARCHintosh project is up - a defrag utility for SD Cards (who had new defrag utility on their 2026 bingo card?) tinkerdifferent.com/threads/new-...

Kicking off #MARCHintosh with the smallest Mac ever: the Pico Micro Mac! Check out the video on Level 2 Jeff: www.youtube.com/watch?v=-gOS...

Check out Ron's new updated guide. It is fantastic. Also, if you don't have a classic Mac kicking around and want to get your #marchintosh on, be sure to check out infinitemac.org That's what I did before I snagged my LC and pico micro Mac. (Woops fixed typo)

The first legit holy shit celebrity I ever met, and to this day one of the kindest. Classy, hilarious and uniquely talented. I don’t have anything else to say. I just love this man.

Many thanks to @engineersneedart.com for this entertaining discussion about the Macintosh classic Pararena! Let's Chat with John Calhoun (about Pararena) - Soft Dorothy Software & Apple Computer #MARCHintosh youtu.be/QpK6fYYr-6o

"Will 2026 be the year the official #MARCHintosh bsky account gets 1,000 followers? We asked these 140 random people on the street their opinion..." @itsmarchintosh.bsky.social

Want a hardware-y way to get your ImageWriter II up on #GlobalTalk in time for #MARCHintosh? Last year I reverse engineered Apple’s LocalTalk option card and made the design available, naming it ImageScribbler: github.com/polpo/images... and pre-built ones are for sale: jcm-1.com/product/imag...

Someone is REALLY unhappy that I woke them up after too many years in storage for #MARCHintosh . 😬

Hell or high water I will get this LC on #globaltalk this #marchintosh if approved! 😄

Give github.com/retrotheory/... BigMaclock a try, It supports dynamic pixel sizing so you can run it on a larger screen. #MARCHintosh

One day before the start of #MARCHintosh and the polpo zone and its ImageWriter II are back on #GlobalTalk! About 5 minutes after getting online I got a letter from John Sculley himself. I’m honored

For Globaltalk, in Marchintosh 2026. 18.5 hours, 1 bit, black and white only. (Original .pict on a bunch of your globaltalk servers)

New video is up. HackerBox 0121 from @hackerboxes.bsky.social is a microcontroller lab kit that really leans into learning by doing. No pressure to be an expert, just room to experiment and build confidence. Thanks to @pcbwayofficial.bsky.social for sponsoring. youtu.be/XEJ-Hc8Tk5k

Made a guest appearance on the latest RetroCombs video! We had some fun playing with LoRa. www.youtube.com/watch?v=QN4E...

Snowy Saturday = @hackerboxes.bsky.social catch up!

In concert with the PicoIDE campaign launching at Crowd Supply, I have released the PicoIDE documentation so you can preview how you can use the device in detail: PicoIDE docs are live: picoide.com/docs/

Woot! Back this awesome project!

@polpo.org joins us this week to talk optical media fragility, "cursed IDE controllers," & more, as ATAPI CD-ROM / IDE fixed hard drive replacement PicoIDE is ready for production. The campaign launches today, see picoide.com for details, and watch this Saturday on This Week in Retro episode 253!

Oof. Thanks Amazon!

Finishing things up for #PicoIDE and it just about saturates the IDE bus in MWDMA mode 2. I’m pretty happy with this! It tests as fast as a 74x CD-rom drive which means there’s a bit more headroom in that mode but that could be the CPU on this K6-2 system being a bottleneck.

It's freezing cold out... So let's drive 4+ hours away to geek out with retro computers! ☃️ youtu.be/ORbsZHp8X6U

I wanted to build one DOS PC. I ended up with a pile of 486-era parts, a lesson in 5V vs 3.3V CPUs, and a reminder of how fast everything changed in the 90s. This one’s less about specs… and more about the feeling. youtu.be/MWojqpaeGgU

I did a complete playthrough (casual mode) of the new game for the Apple II - FROGGO! youtu.be/YNG3ciEM9cc

Dude, why'd you make your music sets have cover art of fake Atari Cartridges? (looks them over) Carry on. archive.org/details/@r_s...

feast your optical orbs on this beautiful LN3-2A aircraft gimbal! www.youtube.com/watch?v=ak5S...

.@actionretro.bsky.social gets his Mac Plus online with a BlueSCSI Wi-Fi www.youtube.com/watch?v=nlT8...

If you thought these were expensive now, wait until we're at war with Denmark.

It was great chatting with @aricwilmunder.bsky.social about what it takes to build a game engine! #maniacmansion #lucasarts #scumm youtu.be/628d6-pTRzI

Oh. Oh no. Steve, no. (I encouraged him, so I'm just as guilty 😈)

Great work by @jcs.org for a HUGE improvement to #BlueSCSI Wi-Fi Speed- will be in the next release but did a quick pre-release build with his branch if you want to try it out today! github.com/BlueSCSI/Blu...

Caught an episode of swindled that covered this Michigan story from the 70s. Horrible. :-( sph.umich.edu/news/2023pos...

Cute new Frogger clone for the Apple II www.lasermego.com/a2sw/froggo

Finally got a chance to try out the picogus properly. Thanks to @polpo.org for sharing such a kick booty creation with the world! Oh, and thx to @museumjoe.bsky.social for selling it to me a while back!

Yay! Looks like I didn't kill it!

Yet again, @bluescsi.com rocks!

. @hackerboxes.bsky.social Hackerbox 0120 video is up. More backlog catchup as I do a walkthrough of what’s in the box, basic demos, and more. Home automation and monitoring ideas abound. Thanks to @pcbwayofficial.bsky.social for sponsoring this one! www.youtube.com/watch?v=Jy_g...

😔

the 3d print didn't turn out very well because of the ridiculous supports it needed but it mostly fits

Loaf of bread, or ImageWriter II? YOU MAKE THE CALL!

Health checkups with ads, we did it everybody

Cleared some driveways. Now chilling with a well dressed bud. 😆

New @hackerboxes.bsky.social 0119 video drop. I'm playing catch up. Check out the fun lil Thrifty Yeti Locator with me. www.youtube.com/watch?v=rKNJ... Giving away 1 of these boxes to one randomly chosen commenter with a US mailing address.
