I finally got around to building a new 8 digit display and mounting the whole thing in place of my floppy drive. The total cost for this project was less than $20. The most expensive parts were the 7 segment displays and the ICM7218 chip. I used 0.56″ tall digits. It took 4 of the LED packages to get 8 characters.”Link.
