IBM RT PC ESDI Magnetic Media Adapter
The IBM R T PC ESDI Magnetic Media Adapter is used with the R 70
fixed-disk drive. You may use up to two IBM RT PC ESDI Magnetic
Media Adapters. The adapter in slot 1 can operate one or two R70
fixed-disk drives in drive positions C and D; in slot 2, the adapter can
operate an R70 fixed-disk drive in drive position E. The IBM RT PC
ESDI Magnetic Media Adapter
will not operate a R40 fixed-disk drive.
Before installing the drive adapter, you must set the jumpers.
To set the jumpers, lift the jumpers off the pins and install them as
