Applications

The Toshiba Libretto was a remarkably compact Windows 95/98-era sub-notebook — roughly the size of a VHS cassette — that Toshiba introduced in the mid-1990s. Because the Libretto 50CT and 70CT had virtually no built-in ports of their own (a consequence of their tiny form factor), a port replicator like the PA2718U was essentially required for any desk-based use. It allowed users to connect a full-size PS/2 keyboard and mouse, a parallel printer, and a serial device, effectively turning the pocket-sized Libretto into a functional desktop workstation when docked. These units are now sought after by Libretto collectors and enthusiasts who maintain working examples of these historically notable ultra-compact machines.
