68008 Microprocessor Kit

Description

This is my 2016 year-end project. The educational kit using a 32-bit computing power, the Motorola 68008 microprocessor. The design is simple with minimum components, however providing a large amount of memory space, 128kB RAM and 128kB ROM. The keyboard and hex display allow us to enter 68000 code to the memory and test run with single step and break point. The CPU status will be saved to user registers for example D0-D7. These are 32-bits registers which can be displayed on the 8-digit seven segment directly. The decoder logics are put into the PLD chip, 22V10. All memory and I/O spaces, DTACK, AUTO vector, boot overlay signals, are written in logic equations. The monitor program was 'c' and assembly codes. Users may modify your own monitor program easily. The board layout is very nice, easy build, and easy use.
