I was a devotee of PC Plus back in the early 90s with my first XT compatible. I have exceedingly fond memories of the 5¼" cover disks and discovering a variety of shareware, freeware, nagware, commercial-but-lightly-maimed-ware and so on. I learnt a huge amount about the PC from their pages too.

Sadly most of the cover-disk images kicking around at archive.org are from the later 3½" cover disk era, by which time I was at college and more focused on Linux, SLS/Slackware, and so forth.
