X65 - 8/16-bit computer
X65 is a retro/modern 16-bit computer that I designed inspired by the architecture of Commander X16 (CX16). It is based on the legendary 6502 / 65816 processors, which, incredibly, are still in production in 2023 and beyond.
X65 is an open-source - you can find all schematic and sources in my GIT repository:
https://github.com/jsyk/x65
Mechanical design files (enclosures) are available in a seperate GIT repository:
https://github.com/jsyk/x65-mech
Blog related blog posts on this site are available under the ling: Category=X65
The same is also published on a hackaday.com project X65-SBC.
License: the electronic (schematic and PCB) and FPGA (Verilog) design is completely done by me. There is no copy-paste from CX16 (whose schematic at the moment is not available publicly anyway), the exception being the VERA FPGA, which is open-source/free and that is acknowledged. Running of CX16 ROMs on the system is subject of their own copyright matter, therefore these are not included in the repository - you have to get them yourself from other location.
