Thanks for sharing that! Never got to see any pro wrapping.

By the time this stuff started, I'd started forgetting all the hobbyist hardware electronics I'd learned (thinking it would last) and had moved to software ... at right about the time that manu's stopped documenting their internals ... but while disassemblers still existed.

In retrospect, it seems almost nuts that appliances from the past came with not only a block diagram, but a schematic. Especially now that everything is not only too complex to be documented "for your own good", and even potential repair techs, and now with DMCA protected software locks.

I still sometimes use the old Scott amplifier my parents got 50 years ago, with manual - and it has everything you need for a repair (besides a list of modern day replacement for some of these, of course). Same with the ol' Amiga 500 in a box over at their house. A lot of tinkering you could scheme on your own without going online (my quartz oscillator overclocking replacement never materialized, but hey).
