DIY ISA game control adapter with parallel IO

Posted on Tuesday, September 12th, 2017 in DIY by DP


Dr. Scott Baker has published a new build:

My Xi 8088 homebuilt PC is running a little short on slots, so I wanted to combine the functions of a game control adapter and an 8255 PIO board. Two functions in one slot. As to why one wants each of these things:

  • A game control adapter is used to interface to PC joysticks. These are the old-style analog joysticks with the 15-pin connectors.
  • An 8255 board is a general purpose interfacing board, providing 24 bits of digital IO that can be configured as inputs, outputs, or a mix of both. This is not in and of itself a “parallel port”, but could probably be used to implement one.
