In this video, I replace the CPU card in my H8 computer with a card that uses the Zilog Z8000 16-bit CPU. I designed this card based on some of the boards from my Z8000 "clover computer" modular computer project. In addition to the Z8000 CPU, it includes 1MB of RAM and 1MB of flash. On-board peripherals include serial and parallel / counter-timer. While it functions as a standalone computer, the real goal was to put it on the H8 bus, so I implemented the necessary transceivers so it can perform 8-bit IO on the H8 bus. I wrote a panel monitor so the H8 front panel can be used. For more electronics projects, see smbaker.com
