How big is the CPU Instruction Decoder PCB?
It measures 93.5 × 32.8 mm and has 4 copper layers, 4.69 mm thick.
What parts does the CPU Instruction Decoder use?
8 parts, built around the 74HC245D and 74HC154D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the CPU Instruction Decoder KiCad files?
From the Trilobyte-CPU/8-bit-computer repository on GitHub, at the commit this page was made from: the board is PCBs/999-QUEUED-TO-PRINT/Instruction-Decoder-Extra/CPU-Instruction-Decoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CPU Instruction Decoder design in my own project?
Its repository states no licence, so its author keeps all rights: ask Trilobyte-CPU before reusing the design.
