Major milestone: my hand-wired Z80 computer just executed its first code from ROM. Verified with an led array after bringing up the ROM, RAM, and address decoder. The first heartbeat of the Zenadi Codex. #Z80 #HomebrewComputer #RetroComputing #Electronics #DIYComputer

Back at it today wiring my custom computer, but I have concerns. I'm confident I can wire it correctly even without a formal schematic. The real challenge is the breadboards—at this level of complexity they're just not a stable long-term solution. #HomebrewComputer #Z80 #TTLLogic

Every retro computer project needs a grimoire. Mine is a Zenadi Codex binder packed with pinouts and 74xx logic references. #RetroComputing #HomebrewComputer #Z80 #Electronics #EmbeddedSystems #ComputerEngineering #Maker #DIYElectronics

I'm building a custom programming language, framework and virtual machine. My goal is to create a revolution and make the browser irrelevant. #ProgrammingLanguage #OperatingSystems #HomebrewComputer #SoftwareRevolution #LowLevelProgramming #TechInnovation

Progress on the custom computer tonight: ✅ ROMs wired up ✅ RAM address lines connected ⏳ RAM data lines next One wire at a time. #Zenadi #ZenadiCodex #RetroComputing #HomebrewComputer #Z80 #Electronics #DigitalLogic #ComputerEngineering

Working on the CPU1 memory subsystem today. Current memory map: Using a 3-to-8 line decoder for memory selection. The ROM is actually 64K, but only the lower 32K is visible for now. The upper 32K will be added later through bank switching. #HomebrewComputer #RetroComputing

Retrofest 2026 in Swindon is not long now - hope to see you there! #retrofest #oldcomputers #homebrewcomputer

Imagine having the skills to just build your own PC from scratch. In 1980, Robert Belleville did just that with this custom built 8080 based machine. It even had its own audio processor and…WOODEN chassis (yum). What’s the coolest custom PC you’ve seen? #RetroTech #HomebrewComputer #TechHistory

#IndustriaTI | El club que inventó el futuro: #homebrewcomputerclub . ¿Sabías que la revolución digital no empezó en una oficina, sino en un garaje? 🚀💻 En 1975, un grupo de entusiastas en California, EU, se reunió con una idea "loca": que las computadoras no debían ser solo para gobiernos o corporaciones, sino para todas las personas. ¿Por qué fue tan importante? ✅Democratizó la tecnología: Pasaron de las computadoras del tamaño de una habitación a las microcomputadoras. ✅Cuna de gigantes: De ahí surgió Apple: Sí, #stevewozniak presentó su prototipo en este club mientras #stevejobs buscaba cómo venderlo. ✅Cultura Hacker: Promovieron el intercambio abierto de ideas y hardware, sentando las bases del movimiento open source. Sin el intercambio de este club, la PC que tienes en tu escritorio (o el smartphone en tu mano) habría tardado décadas en llegar. conoce las anécdotas: infochannel.info/la-noche-en… #ComputingHistory #TechRevolution #HomebrewComputer #SiliconValley #Apple #RetroComputing

Happy Valentines fellow nerds - here are some more blinkenlights to brighten your already great day😍 Now with a 74HC161 counter for additional dynamics!🤓 #74hc161 #electronics #homebrewcomputer #6502diy youtu.be/FOEHbET1tww

It's been ages since I did anything with my 6502 homebrew computer, so here is a video about benchmarks against classic machines from back in the day - always a controversial topic!😂 #homebrewcomputer #mos6502 #basic #80s #6502cpu youtu.be/pQFLyB10Uj8

New video - a dive into RAM banking to explain how a chiptune player (Protracker - PT3) run at the same time as regular programs. Tons of PT3 tunes out there - the 6502 player runs with ~5% overhead. #Chiptune #8bit #homebrewcomputer youtu.be/ABDBaE9197M?si=ZH5I…

I've been so crazy busy with work, but had a chance to make a 2024 update video on my homebrew computer. I've had to remove blinkenlights as the camera couldn't cope with them! #homebrewcomputer #mos6502 #8bitcoders youtu.be/f3mx2mDwbIw

Is this a BBC Micro..?!? Come along to the Retro Computer Festival @computermuseum this weekend to find out what it really is. This and much more besides from a bunch of friendly and knowledgeable retro computer exhibitors! #retrocomputer #homebrewcomputer #8bit

Wow, I nearly forgot about how it started...and how it's going! Still use the green button to this day in the manual reset circuitry! Fun journey from one small breadboard free running a 6502, to a full featured homebrew computer! #homebrewcomputer #breadboard #retrocomputing

Slight weekend progress on Kompik McKomp 16bit ISA Micro ATX Backplane. Will 6 ISA slots be enough? #retrocomputing #homebrewcomputer #retrogaming #martenelectric #motherboard #x86
