Computer "Train"ing

Using commercial evaluation boards in teaching

Manufacturer evaluation boards aren't restricted to the domain of the working engineer. They also make inexpensive trainers for up-and-coming engineers. Check out one board and how it is being used.

Silicon Update

Update Your Design On the Fly

We've all come to appreciate the convenience of updating firmware or logic arrays by erasing and reprogramming the EPROM or PAL. A new batch of chips is now showing up that can be updated while still in the circuit.
