There was one big advantage to starting from a home
computer rather than
just a CPU chip. You had a 'base system' that included enough software to
PEEK/POKE bytes to your homebrew add-on for testing.
That alone made life
a lot easier when you wwre starting out.
Tony! This is exactly the point I was making a few months ago about the
ZX81. At that time, you said you'd prefer to start with a Z80 and build up
from there, while I suggested that the ZX81 was a
better starting point for
a homebrew system since the BASIC and video were
built-in.
Care to clarify?
