Today I finally got around to disassembling that hard drive in my room.
It was a Maxtor 8 Gb, still uses parallel ports.

Circuit board that displays the digits of e
Circuit board display first 16 digits of e
This is the final project for our CP 120 Digital Electronics lab. We are to build a circuit board display first 16 digits of e. It takes in a number (the nth digit) and output that digit of e.
In general, we create the logic equation, reduce it with Karnaugh map, program it with a complex programmable logic device (CPLD), and wire it all up to light up a 7-segment display.
Let’s start:
How does one simplify the work of creating outputs to a 7-segment display?
Traditionally, you’d have to use k-maps, and repeat the process for each lighting diode. This means a lot of errors could result.
So how does one automate the process of creating equations?
Let’s start of by defining:
- Inputs
- Outputs
