I created PicoGUS, an ISA card that can emulate sound cards like the Gravis Ultrasound, Sound Blaster, and MPU-401: https://picog.us I’m a retrocomputing generalist! Also on Fedi at https://chaos.social/@polpo In Colorado, USA

I make things for old computers and like using them in fun ways. Most people know me for PicoGUS, a sound card emulator for mid-90s PCs. I'm making a card for the Sharp X68000 now, and when I get the chance I try to do things like hook an old Macintosh up to barbed wire and print over it.

A PicoGUS 2.0 card - a squareish red board with an edge connector for an ISA slot, a metal bracket, 3.5mm jacks, and a USB-A port.

A somewhat large, squareish shaped circuit board. It says "X68000 dev breakout board" on it with a halftone dot version of the Longcat meme photo. There is a pin header and edge connector slot on the right side of the board.

A Macintosh SE/30 set up on a desk next to a barbed wire fence that is inside in an office-like environment. There is a push button telephone on the fence post. The Mac is connected to the fence with a set of alligator clips.

I don't know if you saw it, but earlier this year a speed fix was released that lets it run on faster machines: www.wcnews.com/chatzone/thr...

So this #SHOT2025 panel has nearly wrapped up. But if you want to read more about historical issues surrounding multimedia and the preservation of born-digital collections, check out this piece on #DigiPres at @theul.bsky.social.

A digital dark age? The people rescuing forgotten knowledge trapped on old floppy disks

From lectures by Stephen Hawking to the letters of British politician Neil Kinnock – it's a race against time to save the historical treasures locked away on old floppy disks.

It's time! After 33 years, I'm adding Gravis UltraSound support to my DOS game engine. 😄

I never owned a GUS back in the day, so it never happened. Now I've got a PicoGUS from @polpo.org (and a great emulator from @86box.net). So off we go!

Step 1A: I mirrored the final GUS SDK (v2.22) on GitHub.

GitHub - RobertSundling/GUSDK222: Gravis UltraSound, PC GamePad, and Analog Pro SDK V2.22 (GUSDK222.ZIP)

Okay, it's time. I have a prized Cult of the dead cow Zippo lighter. These simply do not exist anywhere. But a CDC member is hurting and I want to encourage donations to the GoFundMe, so out it goes. Details in thread.

i drew a 0603 resistor and a capacitor today

an isometric diagrammatic pencil drawing of a single resistor and a single capacitor, with dimensions indicated. the capacitor is taller (by exactly how much depends on the manufacturer). the terminals differ for both, for the resistor they wrap around the ends only, leaving no solderable surface on the sides. for the capacitor the ends are capped, as if the capacitor were dipped end-on into jelly or some kind of glue, or perhaps hot sugar or possibly fondued. but just on the ends

Hey I finally got an everdrive for my NES but it didn’t have a cartridge shell so I just used one from an old sports game and cut a hole for the SD card.

Of course! I even dug into an .mbox archive on archive.org to corroborate.

Stumbled on a reddit thread with people calling a Usenet post from 1994 fake because it was archived on Google Groups. Excuse me while I crumble away to dust.

Our former neighbors who are queer just left for Portugal permanently a couple weeks ago. Their red line was November 2024 and they planned for months to get everything in order to be able to go.

I got my boards around the same time. Seems that par for the course with JLCPCB, they are inconsistent with data entry in their catalog. Some say X-ray is required, some don't, even though they have the exact same footprint. The MSL they have for these parts varies wildly too (datasheet says MSL 3)

Oh jeez me too. It's been 25 years since I've played it but I still remember.
