PC TRAINER is a dynamic demonstrator. This is a fully wired system. This is intended to train the students on the hardware and software features of a typical computer. Using this trainer, a few hardware experiments can be conducted. In order to facilitate better understanding, faults are also introduced by
using Switches and monitor LEDs. This trainer consists of a populated motherboard, keyboard, SMPS, SVGA mono monitor, 1.44� FDD, dedicated I/O card with timer, I/O ports, buffered control, address lines etc. All these are terminated on independent silver coated spring terminals called as patch panel. Each terminal is legend printed for easy identification. It is possible to observe all the following mentioned signals. The entire system is mounted on a study base.

Specifications:

Intel CPU CELERON
1. Memory: 32MB
2. Dedicated interface card which allows various I/O ports (3Nos) programmable timers (3Nos) using 2Nos of 50pin FRC Cables. This Add-On card uses one ISA slot on the motherboard.
3. Buffered control, address, data signals (A0 to A10, D0 to D7, IOR, LOW, REST,MER,MEW,ALEE,AEN,CLK,IRQ7, Pacer clock etc, terminated on a dedicated control panel on 1.5cm silver quoted spring terminal.
4. Signals on the spring terminals duly printed.
5. Separately decoded I/O lines for port expansion.
6. Variable frequency pulse generator upto 100KH with complement output.
7. Crystal controlled oscillator of 5MHz, 2.5MHz and 1.25MHz for pacer clock control. This is terminated on patch panel.
8. Monopulser.
9. Solderless breadboard for connecting external hardware like resisters, capacitors, transistors, ICs and other semiconductor components.
10. Fully assembled in a transparent cabinet.
11. Facility to connect external signals on this patch panel.
12. Standard 101 keyboard, 14� softwhite monitor. 1.2MB FDD. 150W SMPS.
13. Fault introduction facility in Monitor, like vertical hold, horizontal hold, and intensity, GND.
14. Fault introduction in keyboard like CLOCK, DATA, GND +5V.
15. Fault introduction in CPU like Speaker interface, Reset control, RS232 C Serial interface.

The following signals are available to the user for interface, without the following features the PC Trainer has no purpose. Instead any commercially available PC is sufficient.

• Buffered address bus from A-0 to A-19 and buffered Data bus from D-0 to D-7.
  
• 24 additional I/O Lines PA, PB and PC ports from IC 8255.
  
• Access to three timers with GATE, CLOCK and OUTPUT terminals available to the user.
  
• 4 additional I/O decoded chip select lines.
  
• Crystal controlled clock provides fixed frequency of 5Mhz is available on spring terminals.
  
• Control : RESET, I-O/R. I-O/W, MEW, MER, ALE, AEN, CLK, IRQ-7 lines
  
• PC power supply of ?12V DC, ?5VDC, are made available on spring terminals.
  
• NOTE: Short circuit on these terminals will disable the computer from its functioning.
  
• More than 1400 solder less junction points on the breadboard.
  
• All terminals are spring loaded to connect 6 numbers using 22 SWG single stranded wires.
  
• All spring terminals are plated and bright finished for better conductivity.
  
• System is mounted on an elegant cabinet.

Using the above trainer the following experiments can be conducted. You need 15Mhz dual trace oscilloscope and a DMM, for conducting the following experiments.
1. Observation of DATA BUS signals
2. Observation of Control BUS signals
3. Observation of Address BUS signals
4. I/O decoding experiment
5. Experiment in study and testing external gate IC.

Software:

A detailed documentation will be supplied along with the trainer. It covers the following topics in Disk Operating System (DOS). Using this the following aspects can be investigated for experimenting.
1. File specifications
2. Preparing your fixed disk
3. Configuring your system
4. Using TREE-Structured directories
5. Standard Input Outputs
6. DOS commands
7. The Line Editor
8. The Linker Program
9. The DEBUG program
10. Device Error messages
11. I/O interface Experimental programs in BASIC, C, C++ language

NOTE: The Mechanical and Electrical features may change at the time of delivery.
