GSAS 85 is a microprocessor trainer with standard features like small keypad, LED display, monitor program etc, has become a very popular device for training and development, probably due to its low cost. As microprocessor applications have become more popular, the requirement for a more advanced microcomputer trainer with powerful system software and additional hardware started growing.gsas_85

GSAS 85 is Complete single board microcomputer used for software and hardware development in research institutions and R &D labs.

The system firmware provides a stand-alone monitor, assembler, disassembler, Serial monitor and Drivers for EPROM Programmer and Parallel Printer Interface. GSAS 85 is supplied with comprehensive and user friendly documentation as well as windows based communication software with on-line help.

The main features of this board are:
GSAS 85 operates on SINGLE +5V power supply in either onboard keypad mode or from host PC through RS-232-C interface.
