Zeal 8-bit

Zeal 8-bit OS v0.7.0 is out! Big update: • CMake migration (kernel + user programs) • New RAM page alloc/free syscalls • AZERTY keyboard layout & Alt-Gr support • New Python tools • Many bug fixes Check it out 👇 github.com/Zeal8bit/Zeal-… #8bit #Z80 #RetroComputing

Zeal Dev Env by @zoul0813 is now in v0.3.0 ! Still the most straightforward and simplest way to start developing for the Zeal 8-bit computer. New in this release: • TUI menu • Dependency system • More improvements Check it out on GitHub 👇 github.com/zoul0813/zeal-…

This is what Zeal 8-bit Computer can do! Community member AZuech recreated a full Pac-Man clone, named ZPac: joypad support, sound, graphics, smooth gameplay, ... everything is there. And yes… it's open source! github.com/azuech/ZPac #retrogaming #z80

Going further with "Mode 7" on Zeal VideoBoard (homebrew 8-bit video chip), for pseudo-3D: Adding 2 more 16-bit values + hardware division and... Voilà, we get perspective effect! All in hardware, no CPU division, no HDMA!

Adding a "Mode 7" to Zeal VideoBoard (homebrew 8-bit video chip) gives instant pseudo-3D! Just 4x16-bit values and a few multiplications and we get full 2D affine transforms: rotation, scaling, shearing, or any combo Small demo, red square being the player:

@RueNahcMohr How far will Rue go on how small he can get the "hello, world" example for x86? 👀

wtf why is my 32 elf so big? ah, ahh, ok yea, like that. zippo:/tmp# cat hello.sh echo Hello World zippo:/tmp# ls -alt hello.sh -rwxrwxrwx 1 root root 17 Feb 10 16:54 hello.sh zippo:/tmp# ./hello.sh Hello World zippo:/tmp# ;]

Members of Zeal 8-bit Computer community wrote this 3D demo in C! Uses pure software rendering (Z80), bitmap rendering and DMA. Check it here: github.com/Samimimim/Z80-… This PoC got me thinking, how hard would it be to have advanced 2D or pseudo-3D in HW, on Zeal VideoBoard 👀

@ponceto91 C'est mérité ! 👏

Ça y est, 5k sur YT 🎉 Pour une chaîne tech assez niche c'est plutôt bien. Merci à toutes et à tous pour votre soutien 🙏🫶

@RueNahcMohr @Hobby_na_BANJYO It's the Chinese character 并 (combine, merge, ...)

@Hobby_na_BANJYO the parallel symbol looks different... hmm

😱 I got the direction right, but that frightened the hell out of me when I saw it after installing the first battery!

The official documentation can be found here: zeal8bit.com/docs/zvb

Zeal Video Board firmware v1.0.0 is here!🎉 Update it directly from Zeal Bootloader and get new features, including: * Two new bitmap video modes (320x200 and 256x240) * New DMA controller * New Timer controller * Stereo sound, per-voice volume AND MORE github.com/Zeal8bit/Zeal-…

@ponceto91 @xbeaudouin J'attends la vidéo qui va en parler 👀

@zeal8bit @xbeaudouin Oui !! J'en ai eu une d'ailleurs. C'était une carte vendue pour faire tourner CP/M et des programmes 8080 mais c'était bien un Z80 dessus

Dans ma dernière vidéo je vous parlais du Z80, célèbre microprocesseur de Zilog 🔥 Je vous parlais aussi de différents projets hardware autour de ce cpu, comme la RC2014, mais j'aurais dû aussi vous parler de l'excellent projet de l'ami @zeal8bit ⬇️ zeal8bit.com

@arbresvoit @ponceto91 Merci beaucoup! Avec du temps et de la motivation, tout est possible

@ponceto91 @zeal8bit Superbe projet ! Ces initiatives brillent en France, même si le soutien institutionnel se fait discret. Bravo à @zeal8bit, c’est ce genre d’avancées qui montre qu’on ne manque pas de talent, juste de reconnaissance.

@xbeaudouin @ponceto91 Le but était pour pouvoir exécuter CP/M?

@ponceto91 @zeal8bit Je me souviens de la carte contrôleur Z80 sur Apple ][e ...

@hgomez @ponceto91 Merci beaucoup!

@ponceto91 @zeal8bit Très chouette, bravo

@ponceto91 Merci pour la mention spéciale!

@mt_mak3r @RueNahcMohr Maybe😛

My evening challenge to you: Post something Z80.

@NemecekPanda38 @RueNahcMohr I love this approach. The more the constraints, the greater the creativity!

@zeal8bit @RueNahcMohr Unless it's necessary, I try to use the lowest possible processor type - because anyone can do it with powerful hardware, and that wouldn't be interesting. 😁

#WCH80 (ZX80 clone) mini-computer with CH32V002: The BASIC80 firmware is almost done - just need to do some more testing and debugging of functions, write some sample programs and write the manual. The source code took up 5,234 lines of C code and 5,672 lines of RISC-V assembler.

@NemecekPanda38 @RueNahcMohr My bad, I missed that, the video output it similar to the ZX80/1 so I made the assumption it was an emulator 😄 If you need more flash and RAM in the future, it seems to me the CH32V006 may be the solution: 64KB flash and 8KB SRAM

@zeal8bit @RueNahcMohr It does not have enough Flash memory to emulate Z80 instructions - the memory was only sufficient to create BASIC, which is based on ZX80 BASIC.
