The unique design of the DA TA 620/i makes it easy to program,
operate and maintain. The entire mainframe includes the
processor, all processor options, and a 4096-word core memory
in a convenient 10-1/2 inch high rack-mountable package.
Only 17 circuit boards of 11 different types are used in the
basic 16-bit configuration.
Power suppl ies for the processor and up to 8192 words of core
memory are a separate 10-1/2 inch high package that mounts
behind the mainframe. Thus, the entire computer requires
only 10-1/2 inches of a standard 19-inch rack. Installation
is easy, requiring no special mounting, cabling, or air
conditioning provisions.
Maintainability of the DATA 620/i is enhanced by easy front
access to all wiring, making it unnecessary to remove panels
on the computer rack to obtain access to the modu les, con-
nectors, and wiring.
A complete set of software provided with the DATA 620/i
permits rapid preparation of application programs. The system
software includes:
FORTRAN:
DATA 620/i Assembly
System (DAS):
AID:
MAINTAIN:
Subroutine Library:
Subset of ASA FORTRAN.
Two-pass symbolic assembler.
On-line debugging and utility
package.
Complete set of computer and
peripheral diagnostics.
Complete library of transcendental
functions, sing le- and double-
precision and floating-point
ari thmeti c, forma t conversion,
and peripheral service routines.
A wide variety of peripheral equipment is available to provide
the DATA 620/i user with a complete system suited to specific
needs.
