I came across your website and it was in line what I wanted to build a simple hex keypad / display computer. Your work was easy to follow and understand. Great work. I have added another row of keys to the 4x4 matrix using a diode and Nand gate as in the 74c922 datasheet. I can use these keys to go to next location or backwards or run program by jumping to 0300 as in your monitor program. I can email the details if you are interested. Hi Giles.
