LANTastic DOS OS2 Windows

Lantastic is an easy to use, low cost networking system targeted at small networks and home users. It was very popular and highly rated in the early 1990s. Unlike most LAN networking software of the time, Lantastic required only installation and minimal, straightforward, configuration. Lantastic gives users the ability to share printers and files on a hard drive or CD-ROM. It is considered a "peer-to-peer" network, as there is no need for a dedicated server. Any computer may be configured as a server as well as a client. Lantastic was also very memory efficient, using minimal DOS memory in both workstation and sever modes, enabling users to run most popular DOS applications while Lantastic was running. Lantastic supported Ethernet, ARCNET and Token Ring networks. Artisoft also sold networking kits that included both network adapters and the Lantastic software. Lantastic was avaialble for DOS, Windows, and OS/2. At the time it competed against Novell Netware Lite, and many other small LAN oriented products.

Microsoft Mouse DOS Windows OS2

These are drivers provided by Microsoft for the Microsoft BusPort, serial, and PS/2 mice. Introduced in 1983, The Microsoft Mouse is historically important as it was one of Microsoft's earliest hardware products (The other being an Apple II Z-80 CP/M card). The first Mouse for the IBM PC was actually from Mouse Systems, not Microsoft. However, most clone mice emulated Microsoft's serial protocol and DOS driver software interface. The first application designed to make full use of the mouse was Microsoft Word for DOS, and they hyped a product called "Microsoft Windows" (not released until several years later) that was to compete against the upcoming Apple Macintosh and the Mouse Systems based Viscorp Visi On.
