I recently put back an old P3 box (laptops don't have Floppy Disk ports) to access an HP Colorado Backup Tape. 400MB only but some interesting stuff like Word HTML page, some old games, the much nicer than I remember QBASIC.EXE[1] and most impressively TURBO.EXE (Turbo Pascal 7 IDE) which clocks at a whopping 600KB.

[1] that thing had pseudo modules, a visual tracer, live indent and lint (limited but still).
