The HP Colormonitor is a quad-size UNIBUS single-board PDP 11 controller that will - interface to as many as two 0.8-Mbyte HP Colormonitor-D/R dual diskette drives. Data is transfered to the host system via DMA. The HP Colormonitor is an intelligent controller with an onboard T-11 microprocessor. Programs in the host system communi- cate with the controller and drives using the Mass Storage Control Protocol (MSCP) of the Digital Storage Architecture. MSCP and the RUX50 include fea- tures to enhance system throughput, ensure data integrity, and increase subsys- tem availability. An RUX50 can be added to a PDP 11 UNIBUS system in con- - junction with other mass-storage devices. HP Colormonitor-YA UNIBUS controller with 2.7-meter (9-foot) I/O cable. Note: It is recommended that the BC 17Y 1J (20-inch external cable) be ordered - for the second RX50 drive.
