Excited to share a Telnet client I made for #Libre8 — a #DIY computer built from scratch in #Logisim! 🛠️ In this short demo, I connect to a real #Linux machine and interact with it remotely. Hope you enjoy it! 🎥 👉

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!😂

Hello, world! Flashback to last year, when Daisy was still being conceived.

Daisy/2 now has a Moveable Object Block engine with 64 unique bitmaps assignable to any of 32 MOBs, 4 colors per from any of the 256.

Nice Apple II + Atari 800 CHARROM mashup, too!

Yeah, I love this machine.

Adding fun text bitmaps to Daisy II's ROM using the CharROM Editor. Daisy supports 512 totally definable characters.

(Atari ST fans will recognize this fella. SLACK BE WITH YOU. PRAISE BOB!)

I started working towards the BoxLambda OS architecture I outlined in my previous post. I ported Mecrisp Quintus Forth and added a Forth-C FFI:

In the previous post, I outlined the operating system architecture I have in mind for BoxLambda. I’ve now taken the first step toward that architecture: porting Matthias Koch’s Mecrisp Quintus Forth t...

Mich hat sowas einfach immer fasziniert. Wie funktioniert was? Und ich bin Typ "Ich muss das anfassen". Am Ende alles eine Frage, wie man das Gelernte einsetzt. Und was erwartest du von jemanden, der einen handgelöteten luftverdrahteten Homebrewcomputer sein Eigen nennt? ComeOn.

Hab mich für das Kit entschieden. Großes Dock dazu. Fertig. Dann werde ich mal meinen virtuellen Homebrewcomputer in Hardware gießen. 🤷

Installed the 4MHz oscillator, added independent power and reset controls for both Z80s, and upgraded the variable clock with a new speed control. One step closer to a complete development system.

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.

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.

Every retro computer project needs a grimoire. Mine is a Zenadi Codex binder packed with pinouts and 74xx logic references.

Progress on the custom computer tonight:

✅ ROMs wired up
✅ RAM address lines connected
⏳ RAM data lines next
One wire at a time.

Working on the CPU1 memory subsystem today.

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.
One step closer to first boot.
