system to isolate faults to individual replaceable
modules.
Macro-assemblers are available with the 9520
for generating programs for the 8080, 8085A, 8049
family, Z80A, 6800, 6801 and 6802 microprocessors
and, shortly, the 6809, Z8000 and 8086. A linking
loader enables the system to link relocatable
modules and resolve global references. Additional
microprocessor/microcomputer
types will be
supported during 1981.
Also to be provided with the system’s software
is a PASCAL compiler with object code generation
for the 8080, Z80 and 8085 microprocessors.
Operating under MP/M (a multi-tasking
operating system compatible with CP/M), the 9520
uses a sophisticated screen-oriented text editor to
speed program preparation. With the multi-tasking
capabilities of the operating system, the user can
perform two or more functions simultaneously. For
example, text editing on one file can be
accomplished while another file is being assembled
and another printed.
The 9520 can be interfaced to a hard disc
system or a 9580/Host multi-user development
system via its high speed RS422 serial port. In
addition, a wide range of printers and vdu.which
can be readily interfaced are optionally available
from Microsystem Services Ltd.
Like the 9520, the 9580/Host supports high-level
program development with a complete set of macro-
assemblers and compilers for C and PASCAL.
The 9580/Host supports up to eight users via
the operating system, which employs a hierarchical
tree file structure. Programs developed on either
9520 or 9580 systems can be downloaded via high-,
speed serial or parallel links into the 9508 or 9516.
Although more well known for their emulation
and test equipment products Millennium are
actually old hands in the development system
business having been responsible for designing key
Intel and Tektronix development equipment.
