Zeal 8-bit Computer Native Emulator is now public!.* All features of the real hardware supported.* GPU-accelerated.* Built-in debugger.* Full-speed emulation, right on your PC. Of course, it's 100% open-source!.👉 #z80 #retrocomputer

Zeal 8-bit OS v0.6.0 is here!.What's new?.* Dynamic RAM page allocation.* TF/microSD card support.* ZealFS v2 new filesystem support.* Master Boot Record (MBR).AND MORE.Still 100% written in Z80 assembly and open-source!.Check the Changelog on Github:

DMA controller for Z80 <-> FPGA: Done✅ .Copying 55 bytes from SRAM to Zeal 8-bit Video Board VRAM took 6.74us, so ~123ns/byte!.More than 10 times faster than what the Z80 can do @ 10MHz!.This is a game changer for graphics loading or special effects!.#z80 #8bitcomputer #fpga

Zeal Disk Tool, the program I developed to ease ZealFS v2 SD cards creation for Zeal 8-bit Computer is now in v0.3.0!.Lots of new features implemented, such as a ZealFS v2 file browser or disk IMG creation!.

Recall Zeal Disk Tool from last week?.I just pushed a "Viewer" feature to browse, export and import files to ZealFS v2 partitions directly!.This is now the simplest way to transfer data between a host and Zeal 8-bit Computer!.Check it and test it here:

Let's continue hacking the rare Alcatel keyboard I found online and try to interface it with a Z80! .I just published part 2 of the video, come and check it!. #z80 #retrocomputing #zeal8bitcomputer.

I released Zeal Disk Tool, a cross-platform GUI to create ZealFS v2 partitions for microSD and CF cards: ZealFSv2 and microSD support are even beta-supported in Zeal 8-bit OS: #z80 #retrocomputing #zealfs

You know a hardware bug is serious when you have to start plugging the Z80 data or address bus to the logic analyzer! 😅

Here is an Amiga Bouncing Ball style demo running on Zeal 8-bit Computer (Z80 @ 10MHz) natively, at 60FPS thanks to the Zeal 8-bit VideoBoard!. It's open-source so you can take a look here: #z80 #retrocomputing #homebrew

Thanks to @MouriNaruto, it is now possible to browse ZealFS disk images as regular archives on Windows using NanaZip, and it's open source!. Check the latest release on Github: #z80 #zealfs #zeal8bit.

BBC BASIC has been ported to Zeal 8-bit Computer! .This ported was done with a member of the Zeal community. The source code is available on GitHub:

Happy new year!!.A lot of things are incoming for Zeal 8-bit Computer project this year too, so stay tuned!.Here is a small demo, involving sprites and tiles, to start the new year 😄.

A member of the Zeal 8-bit community created a piano/music player for Zeal 8-bit Computer. It can even record tracks, save in files and read them back!.A quick demo here: (Source code on Github: .

What do you do when you find a nice piece of technology but you don't know how to use it or how it works?.It's easy, you reverse-engineer it! That's exactly what I am doing in the video I just released on my Youtube channel:.

Zeal 8-bit OS, the open source operating system for Z80-based machines is now is version v0.5.0!. A lot of bug fixes and new features have been implemented!. Check all the new features on Github:.

Since there are more and more projects related to Zeal 8-bit Computer, I just gathered them in a list on GitHub: Feel free to contact me if you have a project you'd like to add ! 😀.
