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.!!!!! Gerald
