NRI Micro-Master 8000

NRI Micro-Master 8000 is a single board microprocessor trainer based on 8-bit 8085 CPU. The trainer was sold as do-it-yourself kit and was designed to teach the basics of the microcomputers and programming. The MM 8000 was very similar in it's design and functions to the Intel SDK-85 board.

The Micro-Master 8000 was a complete 8085A (5 for 'first 5 Volt microprocessor') microcomputer system on a single board including ROM and RAM memory, a 24 key hexadecimal keyboard, a 2 digit LED display and an 8 single LEDs, I/O connections and an expansion area allowing memory and I/O expansions as well as hardware experiments.

The memory area consists of 2 KB monitor software in the ROM and 256 bytes of RAM. User could enter and read program results through either the built-in keyboard/display or using a serial Teletype through the built-in serial TTY interface.

A large set of assembly and testing manuals were delivered with the board along with the 14 "lessons", which were describing various experiments and functions of the system.
