Tandy Video Information System

The Tandy Memorex Video Information System is an interactive, multimedia CD-ROM player produced by the Tandy Corporation starting in 1992. It is similar in function to the Philips CD-i and Commodore CDTV systems. The VIS systems were sold only at Radio Shack, under the Memorex brand, both of which Tandy owned at the time.

Modular Windows

Modular Windows is a special version of Microsoft Windows 3.1, designed to run on the Tandy Video Information System. Microsoft intended Modular Windows to be an embedded operating system for various devices, especially those designed to be connected to televisions. However, the VIS is the only known product that actually used this Windows version. It has been claimed that Microsoft created a new, incompatible version of Modular Windows shortly after the VIS shipped. No products are known to have actually used Modular Windows 1.1.

Reception

The VIS was not a successful product; by some reports Radio Shack only sold 11,000 units during the lifetime of the product. Radio Shack store employees jokingly referred to the VIS as "Virtually Impossible to Sell". Tandy discontinued the product in early 1994 and all remaining units were sold to a liquidator.

Spinoffs

While Modular Windows was discontinued, other modular, embedded versions of Windows were later released. These include Windows CE and Windows XP Embedded.
VIS applications could be written using tools and techniques similar to those used to write software for IBM PC compatible personal computers running Microsoft Windows. This concept was carried forward in the Microsoft Xbox.
