8088 Microprocessor Trainers   MPT-8088   Downloadable Data Sheet           Specification   Hardware: o        CPU: Intel 8088 runs at 4.77MHz. o        RAM: The system provides on board 32K SRAM, 4K of which is reserved for system, user can use the rest 28K SRAM for applications. 1MB RAM is optional. o        ROM: The system provides on board 32K program memory (EPROM), 16K of which has occupied by system. The other 16K is reserved for user’s application programs. o        Keyboard: It has 56 keys which includes alphanumeric characters A~Z and 0~9 and special ASCII symbols. o        Display: The on board 40x2 LCD module o        Printer interface (Built-in): Standard CENTRONICS interface, which is one of the most versatile general parallel printer interfaces available. The connection cable is the same as those used in IBM PCs. o        RS-232 interface (Built-in): The 8250 controls the RS-232 interface. The protocol can be programmed for different Baud rates, data bits and stop bits. Both download / upload are available. o        I/O expansion slot: The 62-pin expansion slot provides the signals which are compatible with the IBM PC expansion slot. o        Status port: The status port is used to display the keyboard status such as Caps lock, Ins, Ctrl+P. Each of these status are indicated by LEDs which turns on when the function is enabled. In addition, it provides the speaker interface to generating sound. o        Parallel Control Interface: Three ICs are used to provide the Parallel Control Interface. They are 8255, which contains three 8-bit I/O ports, the 8254, which contains three timers, the 8259, which contains five interrupt signals. User can use this interface more convenient instead of connecting through expansion slot. o        Power supply: The power supply provides DC +5V/5.5A, +12V/2.5A, -12V/0.5A.   Software: o        Microsoft Macro Assembler (MASM) Software for 8088 Assembler & Disassembler. o        Memory commands: D-Display, M-Move, C-Compare, E-Edit, and F-Fill. o        Display and Rewrite the contents of Registers. o        Single step program execution and debugging. o        Breakpoint debug: for Setting up to 10 breakpoints for program debugging. o        Numerical systems conversions and calculations, such as conversion from binary to decimal or the addition of hexadecimal numbers. o        Communication routines for Downloading and Uploading between the MPT-8088 and PC. o        Driver routines for RS-232, Keyboard, Printer, LCD display. And BIOS Resume. o        EPROM driver routine (built-in BIOS) o        Demo programs for each experiment (Come with CD)     Built In Basic I/O Experiment Module Specification:   o        50-Pin IDC Connector o        LEDs of 8255 Port A o        7-Segment LEDs o        Thumb-wheel Switch o        8 Pin Dip-Switch o        Tact Switches o        8254/8259/8255 Signal bus o        Selected Switch for signal selection o        10 Application Programs included     10 Application Experiments Program File 1 Racing light BAS1-1.ASM 2 DIP switch BAS2-1.ASM 3 Display 0-9 to 7-Segment LED BAS3-1.ASM 4 5*7 dot matrix LED module BAS4-1.ASM 5 Thumbwheel switch BAS5-1.ASM BAS5-2.ASM 6 Key counter (I) BAS6-1.ASM 7 Key counter (II) BAS7-1.ASM 8 The handshake reading of thumb-wheel switch BAS8-1.ASM BAS8-2.ASM   Hardware Architecture:           o        Keyboard: 56 keys which includes alphanumeric characters A~Z and 0~9, and special ASCII symbols. o        Display: 40x2 LCD module       o        Power Supply : 8 ports which includes +5V/5.5A, +12V/2.5A, -12V/0.5A o        Input / Output Ports : 50 Brass Test Pins & 200 Turn Pins o        Input / Output Ports : 50 Pins IDC Header Socket & Flat Cable
