The insides of an InageWriter II dot matrix printer with a PCB inside - that’s the ImageScribbler card.
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...
Macintosh Plus with 4 MB of RAM and running MacOS 7.1.
Macintosh 476 used as an AppleTalk gateway, awaiting a microSD card with the correct image on it.
Wires found, everything connected, Mac Plus troubleshot and booting, AppleTalk gateway offline … misplaced the drive for it and haven’t found the right image yet 😆 #MARCHintosh

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

It’s been a few years, it is past time to get this cracked Mac Plus back online. #MARCHintosh

A piece of 1-bit pixel art on a simulated Macintosh screen. the piece of 512x342 pixels in size, and depicts a wacked-out bit of art showin the giant number "2026" floating in space over a piece of "Globaltalk" text with an Apple logo next to it. Various spacy shit is around the piece, like a nebula behind, a planet with rings, a small black hole, a whole bunch of stylised magnetar lines, clouds, rocks, and black bubbles of possibly vacuum decay. it's signed in the bottom right corner by me, 'nanoraptor'
For Globaltalk, in Marchintosh 2026.
18.5 hours, 1 bit, black and white only.

On Saturday's noon EST stream, I'm going to attempt repair of a battery-damaged 40MHz 68040 CPU with the help of a $12 Harbor Freight engraving tool. #nojankhere youtube.com/live/fgAGTks...

Screenshot of the PicoIDE Crowd Supply campaign, showing $224,772 and 643% in funding.
Whoops, I missed my chance to make the “640% should be enough for everybody” joke. But it’s obviously not enough because the PicoIDE campaign keeps going. 6 days left! I’m blown away by how far it’s come. BTW the last update I posted brought even more people with weird systems out of the woodwork!

Taking a look at the first Multisync monitor from 1985! Not only from NEC but the first one at retail in general, possibly

The JC-1401P3A displays all standard graphics modes for IBM PCs and many less standard ones, with horizontal sync rates of 15khz, 24khz, 31khz and beyond
