s. 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 ("1.1") 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.
