6530

The 6530 was produced by most 6502 manufactures, from MOS Technology/Commodore SG to Rockwell and Synertek. All production datasheets that I have seen afaik identical, here I present some clean Rockwell datasheets. The first one is a preliminary MOS datasheet for the MCS6530, missing the ordering pages of the production version.
