Designing a Z80 based computer with a backplane for expansion.
This is a small microcomputer based on Z80 microprocessor. This computer is designed in backplane style, they have different cards that able to expand capabilities. The core of microcomputer that contains: Z80, 8KB ROM, 32KB RAM and IO ICs like PIO and UART.
The backplane system uses 40 pins edge-connector integrated on board similar that used on Expansion bus of Dragon Computer.
