It just occurred to me that learning z80 assembly from traditional sources may not be the best idea. After all, the target is an #rc2014, which may be able to take advantage of more modern development methods -- unless if you want to make the little rig do all the compiling and linking itself...
rc2014
I've some offers up on eBay, save a few pounds on some of my hardware for the #SAMCoupe, #ZXSpectrum, #RC2014 & Compatibles, plus my #Chiptune accessories.
Plus some misc. retro related books and magazine auctions.
