Software Product Description
PRODUCT NAME:

BASIC/RT-ll Extensions, Version I, Lab and Graphics Extensions

DESCRIPTION:
BASIC is a high-level conversational programming language developed at Dartmouth College
that uses simple English-like statements and familiar mathematical notations to perform an
operation. BASIC IRT -11 is an exceptionally fast
incremental compiler which gives access to the
RT-II file structure using the BASIC language.
BASIC IRT -11 Extensions (the product includes
BASIC/RT-II) provides:
• Extensive support for one Laboratory Peripheral System for the PDP-II (LPS 11) including
the AID's with programmable gain. DMA and
dual sample and hold operations. real-time
clock. Schmitt trigger. relay. digital 1/0 and
display.
• Extensive support for one real-time analog
subsystem for the PDP-II (AR 11) including
the AID's with unipolar and bipolar gain.
real-time clock. external input and display
control. The AR 11 is a subset of the LPS 11
system.
• Complete support of multiple (up to a maximum of 16) digital input/output subsystems
for the PDP-II (DR II-K).
• Extensive support for the electrostatic
printer/plotter for the PDP-II (LV In
• Extensive support for the display processor in
graphics systems (VT II ).
• Complete support for the alphanumeric and
graphic terminal (VT55) with the hard copy
optIOn.
Since BASIC is a higher-level language. even
the novice programmer can solve complex data
acquisition and processing problems with a minimum amount of effort.
BASIC/RT-ll Extensions also runs in a fully
interactive "desk calculator" mode that can aid
program development and perform one-timeonly calculations in response to console commands without the need for a conventional
stored program.
All commands in this software package are initiated by the BASIC "CALL" statement. The
Laboratory Peripheral System (LPS 11) and the
Real Time Anafog Subsystem (AR II) are fully
supported by the system via modules supplied
with the BASIC/RT-Il Extensions. The realtime extensions enable the user to sample and
display, in real-time, a variety of data.

SPD 12.6.0

Sampling is controlled by crystal clocks and/or
Schmitt Triggers (for LPS 11 onl\') or External
input (for AR 11 onl\') in which ·the user may
specify such parameters as sam pIing rate and response time. The LPS 11 / AR 11 software contains 24 commands. divided into 5 categories according to function. Each category is supplied as
a separate module allowing the user to include
only the modules necessary for a given experiment. The five modules are:
Module 0: Interface to BASIC IRT-ll - always
required
Module I: Analog to Digital conversion
Module 2: Real-Time Clock
Module 3: Digital I/O
Module 4: Display
The electrostatic printer/plotter (LV II) software
allows the user to plot graphic data and print
132 column lines. The software (which must be
purchased separately) enables scaling. drawing
of points. lines and shaded areas and printi 19 of
labels or text. A versatile copying feature allows
programs to create hard copy duplication of the
VT II screen. A total of nine commands in the
LV 11 support software are provided through the
following three modules:
RTDSK RT-Il disk interface
L VSUBS LV 11 subroutine
PLOT GT40 hardcopy feature
The display processor support routines allow the
user to fully use the hardware features of the
display processor such as vectors. alphanumerics.
points. multi-intensities. blinks. etc. Additional
commands perform tasks such as creating and
tagging subpictures (graphic subroutines) and
displaying figures and arrays in one dimension
and two dimensions. The graphic software provides dynamic interaction with the system via
routines for light pen interaction. dynamic
allocation/deallocation of display buffers and
saving and restoring display images as files on
the systems device. Through a total of 29 commands the software provides an uncomplicated ..
flexible and complete interface between the user
and the BASIC /RT-ll system.
The alphanumeric and graphic display terminal
(VT55) software permits the user to fully use the
hardware features of the display terminals.
Lines. graphs, cursors, histogramming. text and
hard copy are enabled. This software enables
the user to fully utilize the graphic and text capabilities of the console terminal through nine
sim pIe commands.
