Hmm, maybe. I find the technical depth lacking in those videos. Hooking something up, or writing a couple lines of basic/assembly isn't anything compared with the list of peek/poke/call addresses in the back of two or three books books from the 1980s. I have the original apple ][+ manual with the assembly listing for the ROMs. I will put that manual up against every youtube video I've seen for technical depth (it also has schematics).
