Operating System: RT-11 V05.01, TSX-PLUS  Source Language: MACRO-11
Memory Required: 1KW (6KW for demo)  Hardware Required: Grant
Technology 306A or 307 Clock Board  Keywords: Calendars, Clock,
Utilities - RT-11
 
Abstract: This package consists of a collection of routines which
provide some basic support for the calendar clock option on
the Grant Technology Systems Corporation model 306A real-time
clock board for Q-bus PDP-11's.  These routines will also
work with the model 307 (calendar clock only) board.
Included are programs to set and retrieve the date and time,
a sample RT-11 device handler for reading the clock
registers, and an example program that utilizes the handler
to produce a running date/time display on a VT100.
 
Assembly conditionals are provided to allow support for all
of the various clock options.  Other conditionals are
included for systems with 50Hz line-time clocks, and for the
assembley of the "set date/time" utility as a
FORTRAN-callable subroutine.
 
These routines will run under both RT-11 and TSX-PLUS.
 
Restrictions: RT-11 V4.0 or later must be used because the .SDTTM
programmed request must be available.
