A versatile, robust & user friendly training system based on the Intel 8086
microprocessor technology. It can either work in standalone mode or PC interface
mode.. Built-in powerful monitor program to enable program entry, downloading,
editing, single stepping, assembling/disassembling &etc to support program
development without haste. A wide range of optional interfacing experiment modules
are also available to enable user to do I/O interfacing with microprocessor and to
view its ends results. This system is bundled with comprehensive manuals, sample
programs and other utility tool.
FEATURES:
• CPU: 8086 (16-bit)CPU
• Operates in both standalone mode or PC interface mode. In standalone mode,
program machine hex codes can be entered into the system memory using the built-
in keyboard and then to be debugged and executed. In PC interface mode,
the host computer is linked with the system for program downloading, debugging &
executing.
• Windows-based software interface/driver for PC link mode
• Communicates with host PC via RS232C interface
• On board monitor program that supports program entry, program edit, breakpoint,
single stepping, program running.
• Built-in Line Assembler/Disassembler in firmware
