Drive of A DRV11-J Interface Supported by the RSX-11M Operating System

  • A DRV11-J interface board is connected to a PDP-11/23 computer under. the support of the RSX-11M operating system in order to acquire the pointing information of a telescope and to transfer the tracking data and instructions to the servosystem. Three methods are introduced to access the interface. A driver which uses a CINT directive to connect an interrupt vector is introduced in more detail.
