Sorta off-topic but...

This is part of that window in time and place that isn't Internet history but isn't the part of the early Web on either. BBSs/PC culture, minicomputers, and various other things exist as sort of a memory hole about which there is relatively extant documentation outside of some memories that may not have been written down at some point. Some things from that era, anything related to Apple, big companies that survived (IBM, HP) made it through to the present day but much did not.
