Software Product Description
PRODUCT NAME:

ADSS-B/F-15, Version SC, Advanced Software System, B/F

DESCRIPTION:
ADSS, the Advanced Software System, is a singletask keyboard monitor system primarily for use with
DECtape. ADSS is designed for res~arch and engineering environments where real-time data acquisition and control functions are combined with interactive program development and testing. ADSS is
an integrated set of programs for the sequential
preparation, compilation, assembly, debugging and
operation of user programs.
The user controls the ADSS operating system by issuing instructions to the monitor. The monitor runs
the jobs, supervises data and file manipulation, and
interacts with the user in a Simple, conversational
manner. This system is sometimes called the Advanced Monitor System or the Keyboard Monitor
System.
B/F, the Background/Foreground system, is a twojob DECtape or disk based real-time monitor system.
B/ F is an integrated set of software designed to
meet the demands of research, engineering, and industrial environments, where one or more real-time
tasks typically require continuous responsiveness
from the computer but do not use 100% of its
capacity.
Under control of the BI F Monitor, real-time tasks are
handled in the computer foreground and have immediate access to the system's resources via interrupts. Background time (time left over between service calls for the real-time tasks) is available for
program development and testing or other low-priority computation in an environment similar to that of
the
Advanced
Software
System.
The
Backgroundl Foreground Monitor contains all the supervisory controls necessary for concurrent processing of background and foreground tasks.
Following are some notable features of the software:
DECtape or Disk-Resident System/User Software all ADSS-B/F-15 software resides on either DECtape
or disk until loaded and run.
Interactive Operation - an interactive keyboardl program monitor permits device-independent programming and automatic calling and loading of system
and user programs.
Programming Languages - a choice of programming languages is given: FORTRAN IV, FOCAL or
MACRO-15.

1/0 Device Handlers - Data and file manipulation
110 device handlers are supplied for standard system peripherals, allowing device independent programming and overlapped computation with the
simultaneous operation of asynchronous peripherals.
Under B/F, mass storage devices, such as DECtape,
disk, and magtape, can be shared between the
background and foreground jobs.
Programmed Monitor Commands - Input/ output
programming is simplified by the use of a set of system commands which are standardized for systemsupported I/O devices.
Conversational Programs - System utility programs
interact with the operator in a simple, conversational
manner.
Dynamic Storage Allocation - the available disk and
DECtape storage is automatically allocated for optimum storage utilization.
. DECtape/ Disk File Structure - This allows DECtape
and disk to be treated as directoried (named file oriented) devices or as sequential access (non-file oriented) devices.
Bank and Page Modes ~ The Background/ Foreground and Aqvanced Software Systems are available in either a bank mode or a page mode version.
In the page mode system (standard PDP-15 system)
user programs are loaded and relocated in 4K word
page units; address modification via index register is
also permitted. The bank mode system is available
to PDP-9/15 users and allows direct addressing up
to 8K words. This system is particularly useful to the
PDP-15 user who wishes to run PDP-9 programs
such as those available from the DECUS library. The
use of the index register for address modification is
not permitted in bank mode. A bank mode system
properly configured can be executed on both a
PDP-9 and a PDP-15.
ADSS Batching Operation - in the Advanced Software System, an alternative to interactive operation
is a batch processing capability of the monitor
which permits user command input via paper tape or
cards. This allows many programs to be run without
operator intervention or supervision.
B/ F Foreground Priority - in the Background/ Foreground system, foreground takes precedence over
background in the following ways:

DEC-1S-XPDAH-A-D

ADSS-B/F-1S, Version SC

SPD 17.6.0

-2Memory Allocation: Foreground is loaded first so
that it can reserve whatever memory it needs.
Peripherals: Foreground, because it is loaded first,
allocates those I/O device which it will use. Those
which cannot be shared with background are then
under exclusive control of the foreground job.
Execution: Foreground execution is triggered by either clock or external interrupts. Four levels of foreground priority are defined so that several tasks can
be combined into one foreground job. Background
runs only when there is no activity in the foreground.
B/ F Foreground Protected - The foreground job is
protected from the background job by both software
checks and by memory protection hardware.

Notes:
1. Two-user FOCAL is available only in PDP-15
page mode systems.
2. ADSS can execute on an XVM processor, however, none of the XVM advanced memory and
addressing features are supported.
3. For a PDP-9 or PDP-15, terminals can be either
L T33 or LT35. On a PDP-15, the LA30C or
LA36 can also be used up to a baud rate of
300. The LA36 is handled as if it were a teletypewriter. The extended carriage and lower
case character set of the LA36 and the paper
tape facility on teletypewriters are not supported.
4. A TC02 DECtape controller with two (2) TU55
DECtape transports can be used instead.

5. The LT15A SUPV~(ts only one terminal. When
more than one terminal is desired, an L T19
control is required in addition to or in lieu of an
L T15A.
6. An RB09 disk system can be substituted for the
RF09 controller with RS09 disk drive.
7. Four (4) RS09 disk drives are logically equivalent to eight (8) single DECtape units. The system can not handle any controller with more
than eight units.
8. The disk pack can be used as a file storage device but not as a system storage device.
9. The LK35 keyboard for the graphics console is
not supported.
10. The two types of disk can not be supported on
the same system.
11. The drum can be used as a file storage device
but not as a system storage device.
12. The disk is not supported as an option in a
DECtape-based system. For the PDP-9, the
RF09 and R809 disks are not supported in the
same system. Four (4) RS09 disk drives are
equivalent to eight DECtape units. The system
can not handle controllers with more than eight
units, with the exception of teletypewriters.
13. The standard 8/F-15 system supports up to six
(6) terminals. One is the console terminal and
the remaining five are connected to an L T19
control (or LT15A and LT19 in possible PDP-15
configurations). During system generation, the
system can be built to support up to 17 terminals, however, four (4) L T19 controllers are
required. The paper tape teletypewriter facility is
not supported. The LA30C and LA36 can operate at speeds up to 300 baud.
