I would like to know if it would be possible, and fairly easy, to make a circuit with a simple 8051,xtal,caps etc, with switches for address lines and data lines connected to a block of NV SRAM or EEPROM so that you could write a program on the switches and run it.


On the very very first micro I programmed, the National SC/MP, the first program I "wrote" was entered on a bank of switches.

Its possible, just nasty....
