I started to work with the Z80 during the first
days of 1998. I have not done anything serious (stand alone project)
with it except for my school project. It is a Z80 based microprocessor
training system. It allows you to load your hex files to the memory
on the system and run that code. You have access to all the available
memory and all the functions the Z80 has to offer. This is so because
there is no monitor software to swallow your memory or I/O resources.
