Yes, the price is printed correctly even though
a computer system with these capabilities might be
expected to cost ten times as much.
The surprising power of this computer system
comes from a remarkable new software operating
system called ETOS (EDUCOMP’s Timesharing
Operating System) developed by EduComp Corpo-
ration. Using this system, a batch stream may be
running from a card reader with output going to a
line printer while simultaneously scuresof other
users may be running timesharing jobs from their
individual terminals in BASIC, FORTRAN IV,
COBOL, or Assembly Language. Or they may be
using the system’s powerful editor to create and
modify data files. And, through the unique virtual
memory technique employed by ETOS, each user
has access to 32K words of memory.

While ETOS is sophisticated and powerful , it
is also reliable and easy to use. Reliability is
assured because ETOS is built around Digital
Equipment Corp.’s dependable PDP-8/E computer
and peripherals. Its ease of operation means that
the system can run all day virtually unattended.
At EduComp, we know educational computer
systems. They’re our only business. You're wel-
come to call on and talk to any one or all of our
100 plus satisfied customers.
In addition to ETOS, we have single-user
BASIC systems for under $6000 complete, time-
sharing systems, and an incredibly comprehensive
general-purpose data retrival system called GPRS.

Educomp’s ETOS was a time sharing multi-user operating system for the PDP-8 that targeted the educational market. ETOS was notable for its use of a virtual memory system that allowed its user-base to vastly over commit a PDP-8s actual physical memory.
Further details can be found be found in ‘ETOS - Multi-lingual time sharing system for the PDP8’ by Thomas Schreier.
