Grant Me StrengthMy retro CPU app is now out. Lots of information on your favourite 8-bit and 16-bit processors. It’s all free too - so give it a look! Instruction sets, pin-outs, sample code and more!
Matt Gumbley@GrantMeStrength Another great app John, looking through the Z80/6502/68000 sections - brings back memories of coding (really bad) games in assembler in my teenage years. So much info in there! I can remember some 6502 opcodes from the days before I found a good Atari 800 assembler :)
