SX-I - Z80 Single Board Computer System
The
SX-I Z80 Single Board Computer System has been designed to teach students
how computers work.
The system is not a copy of early single board computers - this is a
modern rethink of what a single board computer system should be. It grows
with the student to connect to a PC to aid and demonstrate modern methods
of code development.
It starts by takings you through the hardware architecture and a tour
of the boards basic operating functions. You are then taken onto machine
language programming, the Z80 instruction set, the Monitor program and PC
connection.
