These are my notes on building a 8bit computer. The circuit is simulated with the great Logisim, I've also written a converter for my assembly language and a helper to write micro instructions.

• asm contains sketches and final programs written in 6502 or my own assembler.
• circuit holds all Logisim projects, v3 is the latest.
• microcode the microcode program for the circuits control unit (can be read, edited and saved by the microcode editor tool).
• notes different notes on the architecture, memory organisation, opcodes etc.
• tools small software projects to help me designing the computer.
