Olduino/Z State of Play

November 18, 2015

Here’s The current state of the hardware and software. On the left in the image is this Z80 CPU card. The normal ROM has been replaced by a 28C64 8K EEPROM. On the right is the prototype olduino board. It has a standard serial connector, a reset button, and a little avr that generates the 1khz interrupt for timing. There’s a little section of solderless breadboard  which at the moment has two LEDs one connected to bit zero of the output port and the other to bit six.
