B. ANY KINDS
Have you ever play the legendaric digger game (85.073 Bytes)?. A long time ago, this game very popular, but it can run only in PC/XT computer type. I am very fond of this game. Now this version can run in windows dos box (win'9x). The speed can be adjusted.
http://www.geocities.com/dsaproject/downloads/downloads.html Have you ever made a mosquito electronic repellant (186.146 Bytes)? This is another kind of it but all software, man!
This two programs, utilize the PC sound card to become a simple oscilloscope (154.020 Bytes) or a sine wave generator (119.394 Bytes) from BIP Electronics Labs 3 by Marcel Veldhuijzen. Very good display.
I found this program to demostrate the capabilities of PPI-8255 (240.572 Bytes) from Electronics Australia Today, programming as mode-0 ~ mode-2 and any combinations possible. A good example program.
