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...

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'

Whoops, I missed my chance to make the β€œ640% 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!

PicoIDE - Testing, Testing, Testing | Crowd Supply In my earlier update about what it took to get PicoIDE to work on the IBM PC/AT, I focused on just one computer. But IDE/parallel ATA was a standard that made its way into thousands of different systems. How can you ensure compatibility with the large majority of them?

New update on the Crowd Supply #PicoIDE campaign, all about how important my beta testers have been in making it work: www.crowdsupply.com/polpotronics...
