Buried in the Toshiba Canada archives away from sunlight and time, there exists quite the treasure trove of drives and software for classic Toshiba notebook hardware.

Thanks to this hidden archive, I was able to get 16 million colours and sound in Windows 3.x and DOS on my 1999-vintage Libretto 70CT.
