8085 Microprocessor Trainer

8085 based on the processor 8085. It is a versatile microprocessor trainer used as an instructional AID in colleges and universities. It is a complete single board microcomputer used for software and hardware development in research institutions and R&D Labs.

E-8085 operates with single 5v power supply either from onboard keyboard or from CRT terminal/host computer through RS-232-C interface.

- in both keyboard and serial modes, user can enter programs, run them at full speed and debug them through breakpoint and single step facilities.

- MPS 85-3 allows program editing and relocation through insert, delete and block move commands.

- E-8085 allows direct read / write from / to a specified i/o port though in byte and out byte commands.

- it has four onboard spectra strip type ribbon cable connectors for easy expansion and two user defined function keys.

- it supports many types of interfaces onboard text editor, assembler and disassembler facilities in serial mode.

interface modules for training: keyboard, elevator, display, ADC with DAC, dual DAC, logic controller, traffic lights, 8253 demo, RTC, tone generator, stepper motor, numeric printer, 8 bit - 16 channel ADC, 12 bit - 16 channel ADC , opto isolated input, opto isolated output, relay output and study cards.

central processing unit	8085 operated at 3.072 MHz
memory	three 28-pin jedec sockets offer 64k bytes of memory as follows: ROM:16k bytes of monitor program in 27128 EPROM. ROM / RAM:16k bytes user expansion using any EPROM / SRAM RAM:32k bytes supplied using 62256 CMOS static ram with battery backup provision.

interface signals	Parallel I/O:48 TTL compatible lines(2 x 8255) brought out through two 26 pin spectra strip type ribbon cable connectors. Serial I/O:RS 232 C compatible with standard modem control signals through on board 9 pin D-type female connector.

peripherals	8255:one 8255 is supplied to give 24 programmable I/O lines. user can have 48 I/O lines by populating an additional 8255 in expansion socket. 8253:3 programmable interval timers - timer 0 is used for implementing single step facility, timer 1 is used for generating baud clock and timer 2 is available to the user. 8251:for serial communication. supports all standard bauds from 110 to 19200 ( baud is selected through on board dip switch) 8279:to control 32 keys keyboard and 6-digit , half-inch size, seven segment led display. Bus expansion :fully de-multiplexed and buffered TTL compatibles bus signals brought out through two 26pin spectra strip type ribbon cable connectors for expansion.

interrupts	all interrupts except trap are available to user. if single step function is not required, trap can also be used by the user.

power supply	+5 v dc @ 900 m a approx

dimensions	with ABS plastic molded cabinet. l x b x h: 365 x 275 x 55 mm weight:1300 grams (approx.)
