Looks good :)
I'l get some pics when I can of my "home made" bits :D
I am hoping to cheat with the clock at the moment (just till funds allow) ,
I have a half dead Issue3 here with Econet already fitted, I am hoping I can
(temporarily) use this to provide the clock signal (if memory serves, I
think I just need to join two links and hopefully not add anymore
components)
