I've been sick for a few weeks, so progress had to take a back seat to recovering, but last night I had a chance to look at some of the latest code that Ben Eater publisher for his breadboard 6502 (you may recall that it was my aim to make this board pin-compatible with a few current projects others are working on - so far, I've been successful).  and he had started to experiment with the use of the static RAM.  I wanted to give my SRAM a try, so I loaded his code, with some of my own modifications, and here you have it! 

As it stands, really the only thing left for me to test is some GPIO with my pushbuttons, so I'll try and make some time for that coming up!
