Hi Guy's,
My first computer built be me, was the Intel chip 8008. long before the 8080
and the Zilog z80.
I did try the 4004, but it had too many problems.
The 8008 was bootstrapped with switches at first, then I built a diode matrix
to start up the system, much faster, then I interfasted a rom again from
Intel. the memory was 8KB and was driven by the CPU and ana a unit I built to
work with the dynamic memory.
Those were the days when men were men and systems were built by men.!!!!!
