- userbinator 5y agoPIC and AVR microcontrollers can be programmed using a parallel port; passive adapters with nothing more than resistors used to be common.
- nomel 5y agoWhen I was young, I used it for a morse code decoder, and then later to decode magstripe data from a reader circuit I made with spare parts. QBasic made it trivial to interface with! I remember being able to achieve toggles at near a MHz with QBasic, since it was just a memory write. Having that many IO, ready to go, was really great. I bought a separate ISA expansion card so I wouldn't burn out my motherboard's port. Now, you can get a little USB powered micro python board for the same price!
