Hi, I am Zaiphirion. I am building a computer from scratch. This is the beginnings of a prototype called the Zenadi Development System. It uses dual Z-80 processors. It's still a work in progress.

@alphafox The one in your photo. I still own my original.

[Zaiphirion the Eternal ⚔️ @zaiphirion]

@RobertTLange @offlinemark Terry Davis did it first. Just sayin. But serious that is pretty cool.

[Zaiphirion the Eternal ⚔️ @zaiphirion]

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.

There are many social networks out there where I can get lots of engagement. I am not against paying for X but my engagement on threads, and mastodon, heck even bluesky has been way better for free. I may reconsider but for now let's see where I go in those places.

@GlobalNews_24 He's right, it's always been this way. But most people refuse to put themselves out there.

@BillyPacMan The come back PR for Billy Mitchell is top notch.

@BennTan3 @avrldotdev I agree, this example wasn't really good, it doesn't properly demonstrate an exploit, more of a function that always denies access.

[Zaiphirion the Eternal ⚔️ @zaiphirion]

@Tanuki_Bayashin This is some beautiful work.

[Zaiphirion the Eternal ⚔️ @zaiphirion]

@zfunk007 @mooniitani Wow, you need to do more of this! Well done. There are certain YouTubers I watch who only put out a video once a year but they are really well researched and long. Its worth it.

[Zaiphirion the Eternal ⚔️ @zaiphirion]

@mkbtm This is actually a great idea, so much so I'm rethinking the custom Z80 based computer I'm building.

@NitinthisSide_ I've "mastered" C, so much so I am writing my own programming language. It also allowed me the ability to easily learn and master other languages. To be honest, I hate C++, but still prefer it over python which I actually hate more. Mainly because it's just so clunky and ugly.

So, if you are curious. My first “real” video in over 5 years drops tomorrow morning. It’s an interview with Masamitsu “Moo” Niitani who founded the legendary Japanese game company Compile. Here’s the premiere link if you are interested:

@SiliconForested @grok I've used Think C when I began learning to code. Wish I wasn't so intimidated by the Macintosh toolbox, it's not as bad as some of the things I've used in the past.

[Zaiphirion the Eternal ⚔️ @zaiphirion]

@JLCPCB Don't know what that is but it's purdy.

[Matt Thompson @fuzziphy]

Crosspoint switches and CV DACs are successfully under control of the FPGA over Ethernet, with a MIDI controller mapped to issue peripheral CSR updates over etherbone.

I made some Litex Migen modules for both the CH446Q switches and AD5628 DAC with state machines that handle the chip updates from register writes on a wishbone bus, so there’s no softcore required at all.

A small Ratatui TUI app runs with background threads for the etherbone bridge and MIDI control input, and moves messages over channels to issue wishbone bus reads/writes on the FPGA.

@rdotapps Arduino Nano. I have yet to use any of them but I know their potential. Unfortunately I enjoy building from scratch more.

I got the ROM decoders wired up (top left) The ram and rom for both CPUs. I still have a few things to wire up for the second CPU and then test it. The first CPU works, it can execute code in the ROM. I made it execute a familiar instruction to trigger certain lights to blink.
