MTAB 852: MTAB Advanced Manufacturing Technology..........

A microprocessor trainer with standard features like small keypad, LED display, monitor program etc, has become a very popular training and development tool probably due to its low const. As microprocessor applications have become more and more popular, the requirement for a more advanced microcomputer trainer with powerful system software and additional hardware started growing and MTAB 85-2 is a result of MTAB'S conscious effort to satisfy this requirement. MTAB 85-2 has most of the useful features any single board computer user wishes for and the reliability for which MTAB'S products are popular.
MTAB 85-2 is an extremely powerful microprocessor trainer based on the popular 8085 CPU. It can be used as a flexible instructional aid in academic institutions. Sophisticated features like 2-pass assembler and Text Editor allow the use of MTAB 85-2 for serious microcomputer development work in research institutions and R&D laboratories.
Main Features
	On-board Centronics Parallel Printer Interface
	On - board Programmable Interrupt Controller 8259A
	Allows multi-processor system design by supporting the HOLD and HLDA signals
	MTAB 85-2 can be operated either from on board Keyboard or from CRT Terminal /
	Host Computer through its RS-232-C interface.
	Text editor permits line-oriented editing facilities for ASCII files and saving & loading
	of files using audiocassette
	2-Pass Disassembler, disassembles the object code into standard INTEL mnemonics,
	converts all branch and subroutine addresses into labels for easy reference
	32K Bytes of CMOS static RAM with optional battery backup. Total on board memory
	can be expanded up to 64K bytes
	STD bus compatible signals available on the ribbon cable connector for easy system
	expansion
	2-Pass Assembler can assemble any memory- resident assembly language program.
	Supports all the standard INTEL mnemonics, useful directives like ORG, DB, DW, DS,
	EQU, SET, etc. Supports labels of up to six characters.
	Keyboard and Serial Monitor programs support the entry of user Programs, editing &
	relocation; debug facilities like breakpoints & single-stepping, direct port input/output
	and full speed execution of offer programs
