Microprocessor trainer Model MPT-85, is an 8085 trainer. Using this trainer, students studying in, electronics, electrical, instrumentation, mechanical, chemical engineering subjects, B.Sc. (electronics, computers, and physics) slaboratory, and polytechnics can learn programming an 8085 Microprocessor. This can be used for designing prototypes. The instrument is supplied with 48K memory, 32K EPROM and 16K RAM expandable to 64KB using an additional 27128 EPROM. RAM is battery backed using a NiCad battery. Using two numbers of on-board 8255, Input/output interface experiments can be performed. Several experimental interface modules can be connected to this trainer. They are ADC, DAC, Stepper motor, 8-bit switch input, 8-bit LED output, Relay interface module, etc, and many more are available. The instrument has a 50-pin Flat Ribbon Cable (FRC) connector, for interfacing Programmable Peripheral Interface (PPI) chip 8255. The instrument has 22 re-programmable keys. Using OPTIONAL Editor Assembler software, the user can enter their programs on the computer?s screen in Mnemonic fashion directly with the help of the computer keyboard. By the use of this software, the user need not hand edit Opcodes by looking into the Opcode chart. The software directly reads the mnemonics and creates Downloadable opcodes and data automatically. This helps in developing the software and interfaces faster than hand editing programs, and eliminates possible errors at any stage. This has the facility to enter / edit: Labels, comments, redefine start address (Origin) of your programs, data segments, etc. This software can create automatically, Assembly files (.asm) for generating your programs and for eventual storage on storage media, Text files (.LST) for documentation purposes, Hex files (.HEX) used for Download operations Essentially designed to teach the study of: - Instruction set of 8085.
- Familiarize the components used in typical MICROPROCESSOR based instruments.
