Mad respect for Lua. Milestone tonight: Lua 5.1 REPL + VM running on a 6809 #retrocomputing #8bit

Doesn't look like much but it's Rust code running on a real 6809. Rust → LLVM IR → 6809 asm. #retrocomputing #8-bit

Getting wild on Friday night playing Photo Hunt re-implemented in Rust, running on LicheeRV.

It boots OS-9! Anachron8, my 6809 homebrew on an ECP5 FPGA (ice-sugar pro), now runs NitrOS-9 Level 2 from its own boot menu, with DriveWire disks, two screens and a browser console. #6809 #NitrOS9 #FPGA

My 6809 retro-computer now has a debugger on its ESP32 video card.

Lua 5.1 on real 6809 hardware 🎉 Bytecode compiled on the Mac, loaded into my FPGA 6809 through its 1985 monitor ROM, and fib(10) comes back 55 on a WiFi-served text screen. As far as I know, a first for the 6809.

So yeah Megatouch Maxx DOS generation, Mega-pwned. Wrote a Dallas DS1991 MultiKey device for 86Box. ADHD: do a B-Sides LV talk in 2016, then wait ten years and finish the work in 2026.

Had some fun reverse engineering Megatouch games from the DOS era this weekend. I have a pretty good picture of how they evolved and changed their approach to preventing piracy over the years (post coming). At this point I've completely pwned the Maxx DOS generation games.

The show said its name change was “inspired by the bravery and patriotism of Apple and Google,” both of which have complied with executive orders from Trump to change the names of places like Lake Ontario to Lake America.

Fall is depressing, but at least there’s tomatoes!

Wow. This was locked away in a region of my brain I didn't know about.

Apple: Think Different is now Apple: Think Compliant

We're not changing the name of Lake Ontario. Name it whatever you want at your leisure: https://gulfof.mapquest.com/lakeontario (tag us so we can see your work 🙂)

What a fantastic read! aresluna.org/the-hardest-...

Road tripping from Guelph to Halifax. Worst charging situation by far is Lower Sackville, it’s a desert for fast charging. Closest chargers are 15m and all offline for maintenance. Meanwhile, the public library in Hubbards (pop. 2k) delivers!

First 🍅 of the season 😍

What! So cool.

❤️❤️❤️ This. More this please. Less of that other shit.

First time I’ve got an orchid to bloom a second time!

TIL Orion Artemis II has better internet than a lot of people on Earth. 260/20 Mbit down/up. The tech works (at reduced speeds) up to HALF A BILLION KM away! ntrs.nasa.gov/api/citation....

So good.

This was built for ADHD. My closet is a chair, the floor and another chair.

Big pothos is big!

Watch Now ⚡️ "A Wave of Hope" → "Ruby Waves" → "Lonely Trip" → "What's Going Through Your Mind" from Phish's 1/29/2026 show at Moon Palace, Riviera Maya: youtu.be/tX9IZqBj4SQ

Woot! It’s alive, this is a C test program running on my 6809 computer with an ESP32 ‘video card’ hosting a JavaScript console over WebSocket. #retrocomputing

A Python Textual UI for MC6809 to run the ported Lua VM. Ported source and nix flake for building it, and the test harness, etc: github.com/blark/lua-6809

Ha! I got the Lua VM running on the 8-bit 6809 processor. 🤯 #retro_computing

Here is a flake for building the complete gcc 6809 toolchain on nix: github.com/blark/gcc680... #6809 #retrocomputing

Not sure if any other person cares about this, but... it's a major milestone. C code, compiled on arm64 macOS, using newlib libc, running on my 6809 computer.

Woot. Finally got gcc6809 compiling on macOS arm. Merry Christmas nerds!

One reversed tantalum cap (poof), and screwed up connector (why is it right to left!?) ... it lives! Here's a Python + rich TUI doing debugging /w ESP32 using OpenOCD.

Pro tip: don’t put a tantalum capacitor on backwards, you’ll let out the magic smoke!

Reverse-engineered the RF protocol for Zemismart (dumb, sub GHz RF only) motorized blinds 🪟 433MHz OOK PWM. Full protocol docs, Python encoder/decoder, and sample captures. #rfhacking #sdr #reverseengineering #homeautomation

Weekend PCB design fun, CC1200 PMOD. Basically a copy of their 433MHz reference design. If anyone is interested maybe I'll put some on Tindie.

While building a home k8s cluster I had a DNS issue that led to incorrect system time, causing the node to fail when joining. So of course now I'm on a side mission building a stratum 1 NTP server using an nrf52840 + u-blox GPS, in Rust. a) We take GPS for granted, b) ADHD 🐇💫

Daughter disappeared carrying the cat… ten minutes later:

Wow, Orange Pi 6 Plus (CIX P1) whoops rk3588! Got NixOS running on it today... #orangepi #nixos

iPad Pro M5 looks very nice, but at >3k for a decent spec, when you realize you can't even have a full shell on the thing, it's ridiculous. What is "pro" about this? This is not an original take, I know - but worth loudly complaining about until Apple wakes up.

Got annoyed with having to remember how to build uboot for Rock5b so I made a Nix flake. github.com/blark/rk3588...
