Although Digital Equipment Corporation is liquidating its remaining Rainbow personal computers, the 300,000 to 400,000 installed Rainbows are not dead. Suitable Solutions, Inc., is reviving it by offering an accelerator board that upgrades the Rainbow to an IBM AT-class computer. Called Turbow-286, it includes an 80286 CPU chip that runs at 12 Mhz; 64 KBytes of 16 bit, zero-wait-state static RAM; and support for an 80287 coprocessor. It is installed between the memory and mother board on the Rainbow 100B or 100+ models, and is claimed to increase the speed of the system by two to five times. The product is compatible with all existing add-on boards, such as memory and hard disks, as well as operating systems like MS-DOS and CP/M. Turbow-286 is available now for $595.
The company is also developing drivers to enable Rainbow users to run Microsoft Windows. In addition, Suitable has an exclusive arrangement with Digital to work on an enhancement product that will permit Rainbow users to run MS-DOS 3.1.
