A computerproject based on the Z80 CPU.
Motherboard with Z80, 8 kB ROM and 32 kB SRAM, IO ports, Bus ports etc.
- Schema, PCB designed
- Produced and tested. OK so far...
Clock, Reset etc.
- Schema, PCB design
7x4-segment display and IO-connections to adress 0-3
- Schema PCB design
Hex values input keyboard
- Schema, PCB design Needs redesign
Arduino code and design for an Arduino Nano (or similar) based EEPROMprogrammer
- Schema, PCB design Connected to the computer using BUSRQ to facilitate programming without removing ROM.
Python simulation of the z80 cpu and the computer
- Inkludes 7x4 display Many opcodes not simulated yet
Holder for the Dator PCB
- 3D printed and tested
KiCad, FreeCAD, Python, Arduino IDE
