How to build a homemade tester for TTL 74xx series ICs?

IC Tester

I'm new to electronics and currently taking a Logic Design course in which we use breadboards for experiments. In the lab we have tester for our experiments. I wish to make my own tester in order to do experiements at home. Our experiements deal with simple logic gate mirco chips, decoders, adders, encoders, and latches. So I would only need to test for the logic states of those types of chips. I'm looking for advice on designs to build a homemade tester for various TTL 74XX series ICs. Any thing will help here guys.

Not difficult ...

You need:

1) Power Supply (e.g. +5V)
2) LEDs (as indicator)
3) Push Button (to simulate input states)
4) Switches (to simulate input states)

You can use a parallel port interface project in which You use C language program to send pulses of 0's and 1's on the input pins of the IC and then read its output pin.
After that you check the readings with the truth table of the IC.
I think if you are a beginner it might be difficult for you but you can work with a C programmer who knows about parallel port interface
