The Programmed Data Processor -1(PDP-I)
is a fast, generat purposedigital computer.
It is a single address, single instruction
stored program machineoperating in parallel
on eighteen bit one's complement binary
numbers. Two special arithmetic instructions,
multiply step and divide step, are the
iteration steps for multiply and divide.
Muktiply takes approx. 350 microseconds
and divide about 600.

R i p fop Type 1201, ohe of the standard DEC
System Building Blocks used in PDP-1,

The Programmed Data Processor is
assembled with Digital Equipment
Corporation's re1iable and we4 I proven System
Building Blocks. The PDP-I is fast and
competent yet relatively inexpensive because
of the unique combination of speed and
versatility of these Building Blocks.

STANDARD EQUfPMENT
Flexwriter for reader, punch and input-outpvt typewriter.

or
Separate input-output typewriter, punch and
photoelectric tape reader.

OPTIONAL EQUIPMENT
CathodeRaytube display
Magnetic tape
~eahirneclock
Analog equipment
Special equipment as required

input-ou@& system of POP-1 is simple an,d flexible.
If ~irfluhnpousoperation of severaCdevices is required, a
s m b l multiple seqwnce automatic interrupt system is
available.
