Buying the right Computer is an important step. But for
the man who has been through it before, only the flrst.
The headaches may still be before you. (Will you get your
project done on time? Are the peripherals available and
as useful as you hope they will be? For a Computer with a
small price tag, have you really bought enough?) PDP-9
hardware is bigger than you think.
And the Software calms jittery nerves.
PDP-9 ADVANCED SYSTEM SOFTWARE package
as-sumes that you do your own applications programming —
and, then, proceeds to make the job easy, practical, and
understandable.
For example, you can program real-time data collection
and complex analysis in FORTRAN IV, macro assembly
language, or a combination. Both languages produce
compatible and relocatable object codes that make
linking subroutines easy. You can call MACRO-9
sub-roütines from FORTRAN programs and vice versa.
Real-time monitors control the asynchronous operation
of I/O devices, and allow complete device-indépendent
programming. This permits you to change the 1/0 devices
at object time without recompiling or reassembling your
programs. The monitors automatically load the necessary
device handling subroutines.
The conversational keyboard monitor, available on all
PDP-9 systems with bulk storage, permits simple operator
communication. You can compile, assemble, store, load,
debug and operate with simple teletype commands.
FORTRAN IV, MACRO-9, monitors, 1/0 programming
system, peripheral interchange program, debugging
system, editor, relocating linking loader.
1-usec cycle time, 8,192 18-bit words of core memory,
(expandable to 32,768 words), high-speed paper tape
reader and punch, teletype, real-time clock, and the most
comprehensive set of options available.

for it at the Fall Joint Computer Conference.
