Sidekick 1.0 for Windows

Borland Sidekick is a DOS based PIM (Personal Information Manager) and one of the first widely-used TSR (terminate and stay resident) programs. The key feature of Sidekick was that one could use Sidekick's utilities while using most other MS-DOS applications. This was important because MS-DOS had no built-in multi-tasking or task switching capabilities.

Later versions for OS/2 and Windows were simply a bundle of a similar PIM and utility programs.

Sidekick competed against a number of similar MS-DOS TSR utilities such as Popcorn Desktop, Sidekick was marked alongside Borland SupeKey.
