More MOO-related pixel art

Rednex's publisher has decided that me playing their game, which included 10 seconds of their music in-game, was not "fair use." Even though it quite clearly is. Another case of YouTube's copyright system being absolutely broken as fuck. I have no choice but to relinquish monetization of that video.

Don't copy that floppy. It says so. #retrocomputing

From Infoworld, July 1983. My guy generated SIX FEET of code. How many feet of code did you write today? #retrocomputing

I've officially released my real-mode emulator CPU test suite for the Intel 80386. github.com/singlestepte... #retrocomputing #emulation

Disassembly (+ comments) of tape protection of Repton (Acorn Electron). Interesting protection measures. Hidden data in tape block headers is my favourite trick github.com/0xC0DE6502/t...

A rare example of Vault Corporation's "PROLOK" copy protection scheme on a 3.5" floppy disk. Vault used some method - probably a laser - to remove the oxide coating from one side of the mylar disk, making it impossible to write to. #retrocomputing

I used to watch/research up to 10 hours of video on YouTube every single day -- but I spent less than 10 hours doing it. I just released a video where I document all of my YouTube viewing speedhacks I've figured out over the years: youtu.be/B1yHK_nEKaM

Before I got deep into the retro computing hobby, I dabbled in watercolors. My art desk is now an electronics workstation cluttered with equipment and various Arduino projects. I kinda miss painting though. I wish I had the space to have both hobbies. #watercolor

made a lil mascot for my MOO-format for emulator CPU tests i've always done pixel art in photoshop but maybe i should try aseprite someday

I recently did an interview for EX! Magazine, published by Adventurous Music. I talk about art, music, tech, and privacy/security in the age of authoritarianism. It's packaged with some great music by great artists too! 📖 PRE-ORDER → adventurousmusic.bandcamp.com/album/ex-zin...

@davidxnewton.bsky.social i recently found some assets from a DOOM TC I started (and never had a hope of finishing) sometime in 1995 LION KING DOOM

This CrowdSupply item - the ESP32JTAG - just went live, and it has a lot more functionality than I thought it would when I first heard about it. Impressive. Also, 40% of the way to its target, and it only started a few hours ago. www.crowdsupply.com/ez32/esp32jtag

I take no credit.

I've now submitted my entry for the #DOSember Game Jam 2025. I've ported my Psion & ZX Spectrum game #Barbarians to #dos, as usual aimed at the original #ibmpc with #cga graphics. Download it from cyningstan.itch.io/barbarians-dos

Calling for help from the #retrocomputing community! Help us verify extraction of the Intel 8087 Microcode ROM! 8087.martypc.net

Added a bunch of my old vic-20 demoscene sourcecode onto itch. 4mat.itch.io/music-drivers

I’ll be here talking about making games for retro machines alongside other better game developers www.computinghistory.org.uk/det/74558/Re... Also lots of very cool #RetroComputing and #RetroGaming collections

I Have No Mouth, and I Must Scream has been updated on Steam and GOG for PC, Mac, and Linux with added achievements, soundtrack, cloud saves, and more! 😱 📜 Patch Notes: nightdivestudios.com/i-have-no-mo...

My humble (if cluttered) workbench. This is my cozy place!

Take a deep dive into the NEC V20 CPU die at 5 gigapixel resolution, thanks to oldbytes.space/@infosecdj@i... siliconprawn.org/map/sharp/lh... #retrocomputing

I've decoded the NEC V20's group decode PLA. This PLA takes an 8-bit opcode (and two mode signals) as inputs and produces 14 status outputs that control operation of the CPU. These status signals will hopefully explain some gaps in functionality that the microcode doesn't cover. #retrocomputing

The latest version of the Taito F2 core fixes the shadows in PuLiRuLa so they "shimmer" like you see in the video. The shadows are just the character sprites drawn with a black color palette and scaled down vertically. So what makes them shimmer?

Here's a visualization of the NEC V20 microcode showing how the microcode is organized into logical sections. Over half of it implements the 8088 ISA, with many of the internal functions implementing common routines for division, multiplication and string operations. #retrocomputing

I've made some progress decoding the NEC V20 microcode. I'll be updating this thread on VCF: forum.vcfed.org/index.php?th... If you feel like helping out, check out the attached spreadsheet and see if you can identify any of the unidentified source/destination addresses. #retrocomputing #emulation

Here's the microcode ROM from the NEC V20. Cycle accurate V20 emulation? If we can decode it... #retrocomputing #emulation

I'd like to shoutout @pcbwayofficial.bsky.social for sponsoring this run of my #ArduinoX86 V4 boards. The FPU board is my first 4-layer board so I'm hoping I didn't make any fatal mistakes. #retrocomputing #emulation

My talk on #ArduinoX86 from VCF Midwest is up on YouTube! www.youtube.com/watch?v=m_C7... #retrocomputing #emulation

hey @hackadayofficial.bsky.social you have an active phishing campaign going on on hackaday.io here's the phishing account: hackaday.io/SupportAlert

We fixed the vintage IBM printer at the Computer History Museum yesterday. Introduced in 1959, the IBM 1403 line printer provided fast, high-quality output, printing 132 character lines. Unfortunately, one column stopped printing, so we disassembled the printer to fix a bad hammer. Keep reading...

One of the very best write-ups of any demoscene effect I've ever read: cobbpg.github.io/articles/nuf... Bit-banged multiplexing taken to its extreme.

I'm honored to have been able to contribute a new pixel-art logo for the excellent Macintosh emulator, Snow. snowemu.com #retrocomputing #emulation

It's been frequently noted how much better the CGA card would have been had you been able to define the graphics mode palettes - Well, the Seequa Chameleon had you covered. Set all three foreground colors in either palette to any of the 16.

@mcjonestech.com The boot sector of the CP/M boot disk for the Seequa Chameleon is 8088 code! I suspected one of two possibilities, either the BIOS bootstrap detected the CPU type based on the boot sector, or the boot sector itself would change the executing CPU. Looks like the latter.

Post a mage! Here's a powerful looking chap from an amazing demo for the original IBM PC and the CGA card (no really!) called Area 5150. www.youtube.com/watch?v=fWDx...

I'm still not really great at using solder paste. Here we are fixing a few resulting bridges.

One of the highlights of #vcfmw was being able to talk to @jeriellsworth.bsky.social at some length. I got to show her my ArduinoX86 boards. It felt a bit like this

One of the cool things I saw at #VCFMW was the Seequa Chameleon at an exhbit by @mcjonestech.com This was a series of PCs that could switch between a Z80 and an 8088 CPU. Conspicuously lacking ISA ports - there's a CGA integrated onto the board (note the MC6845).

VCF Midwest was a lot of fun! Great meeting people like Adrian from Adrian's Digital Basement, Jeri Ellsworth, Clint from LGR, polymatt, crazyc, TD-Linux, and a ton of other fascinating and brilliant folks. Gave out a ton of stickers! #retrocomputing

Packed up my boards for VCF. I'll be giving a talk on ArduinoX86 on Saturday, at 11AM I think the demo will blow your mind, come check it out! #retrocomputing

Excited for VCF Midwest in two days! Hope to see you there :) #retrocomputing

Performing final equipment check for #VCFMW 2025

My test generator is very close to being able to produce a real mode CPU test suite for the Intel 386. I've made several additional improvements over the 286 test generator, which makes me think I'll go back and regenerate the 286 tests when I have a proper PCB for that. #retrocomputing #emulation

Here's a peek inside a CodeTAP-386EX In-circuit emulator from Applied Microsystems Corporation. There are two large Xilinx FPGAs and a ceramic package bondout 386EX. And bodge wires. Lots of bodge wires. #retrocomputing

The extended clock line on my V2 386EX board has been problematic. I've redesigned V3 as two separate boards, with the FPU board stacking on top of the CPU board. This keeps the clock line the same length if you don't have a FPU, and reduces the length when you do.

Just launched my first ZX Spectrum Next game: Shift A monochrome puzzler where reality flips... inside becomes outside, light becomes dark. 45 levels. 1 secret. Free / pay-what-you-want: h4plo.itch.io/shift Hope you enjoy the mind-bend! ZXSpectrumNext #IndieGame #RetroGaming #PuzzleGame

Remember the Turbo Button on old PC towers? We thought it was warp speed… but it usually slowed things down so old games wouldn’t break. 🤯 Did you fall for it? #TurboButton #RetroPC #90sNostalgia #RaisedWithoutWiFi
