8088 Microprocessor Trainer

E-80882 is a powerful, general purpose microcomputer trainer which can be operated either with 8086 CPU or 8088 CPU. It is usually supplied with 8086 CPU. To install 8088 CPU, user has to just remove the 8086, install 8088 and set a DIP switch. In either case, the CPU is configured for operating in the Max. mode. On-board provision exists for installing 8087 Numeric Data Processor. The system is versatile and can be configured in a variety of ways via jumper options, to suit specific user requirements. The basic system can be easily expanded through the System Bus connectors. 32K Bytes of powerful firmware provides keyboard monitor, serial monitor, single-line assembler, disassembler and driver programs for Centronics compatible parallel printer interface. The software for the optional PROM programmer interface and audio cassette interface is also included in the firmware. E-8088 is supported with comprehensive and user-friendly documentation

The communication software package supplied with the trainer allows E-8088 to be connected to a PC compatible Host Computer System. All the standard commands of the serial monitor of E-8088 is fully supported by this package. In addition, object code files (generated using PC native tools like Macro Assembler) can be downloaded into E-8088 from the Host Computer System, permitting the development of powerful application software. All these features allow the use of E-8088 as a convenient instructional and teaching aid or as a powerful development tool in R&D labs and industries

- Operates with on-board keypad or with a PC compatible system through its RS 232 C interface.

- Powerful system monitor permits entry of programs, debugging through breakpoint and instruction step facilities.

- Interface Modules for training: Calculator type Keyboard, Elevator, Display,
- ADC using DAC, Logic Controller, Traffic Lights, RTC, etc.
