Many manufacturers, such as Western Digital, produce high-density diskette adapters for XT-style computers, and these may be used successfully with RainDOS. That is, a high-density drive must be used with a high-density adapter. The diskette adapter on your computer must match the diskette drive characteristics. Further, your computer must be equipped with either a 5.25' high-density (1.2 Megabyte) or 5.25' 'quad' density drive, such as the Teac 55F.
Computers such as the Tandy 2000 or the Zenith Z-150 are not suitable because of their relative incompatibility. To use RainDOS, your computer must be PC AT-, XT- or IBM Personal System/2 compatible. Under DOS 3.2, the utilities FORMAT, DISKCOPY and DISKCOMP are supported, as well as normal DOS read and write operations. RainDOS is a device driver which supports reading and writing of MS-DOS diskettes from Digital Equipment Corporation's Rainbow tm series computers on PC XT- or AT-compatible machines.
