I recently added a piece to the System 80 site. It was a narrative by someone who restored their System 80 but had also modified/upgraded it beyond belief. It’s a good example of what was called “hacking” back in those days (‘70’s-early 80’s) before spotty teenagers with modems hijacked the term.
Anyway, if you are interested the URL is here.
