My high school's library had a collection of Byte magazines going back to the late '70s. The older issues were full of interesting articles, including some cool hardware and software hacks for the Apple II and other 8-bit computers. This lasted until the early 1980s, but by about 1985 Byte had become a boring PC-business-clone monoculture.


I auctioned off Byte 1 vol 1 a couple years ago and sold the rest. I recall the rare Apple related article, but I looked through them before I sold and most of the stuff was S100, Klugeharp, 8008, 8080, 6800 (Mitts, the first MS BASIC interpreter). All the early heavy lifting was by Carl Helmers and he just wasn't a single address guy (people call it load/store these days for some reason). The two address folks could not seem to grasp the simplicity of the single address architectures. They needed a MOV instruction or they were stuck. They also seemed a bit perplexed by memory mapped I/O and felt better with separate I/O instructions.

They were very excited by the truly goofy Z80 when it came out.

6502 programmers migrated to RISC much easier than Intel users.

Yep--I recall describing the 6502 as a proto-RISC architecture,
where page 0 is really 128 general registers.  The clever pipelining
of the 6502 gave it a CPI advantage that was radical at the time.

However, by late 1980, Byte was beginning to have a lot of
articles relevant to the Apple, perhaps just from sheer force
of numbers.  ;-)
