Well, I learned that this is not true... So I built a small adapter that lets you use a PS/2 keyboard with an IBM 5150 or 5160 (XT) computer. It was a great learning experience :-)\n\nHow to build the adapter\n------------------------\nBuilding the adapter is quite simple. All you need is:\n\n1. a 5-pin DIN 41524 plug \n2. a PS/2 socket\n3. an ATtiny85 microcontroller (optionally with socket)\n4. a prototype board\n\nSolder the PS/2 and DIN 41524 connectors according to the schematics and adapter.fzz\n\nUse the Arduino IDE to build the code and upload it to an ATtiny85. \n\nFiles\n-----\n\n|File                                                | Description                                                  |\n|----------------------------------------------------|--------------------------------------------------------------|\n| capture/*                                          | Bunch of protocol captures, captured with saleae Logc 1.2.18 |\n| schematics/adapter.fzz                             | schematics for the breadboard in Fritzing                    |\n| schematics/adapter_bb.png                          | PNG export of breadboard schematics                          |\n| schematics/adapter_bb.svg                          | SVG export of breadboard schematics                          |\n| schematics/DIN-Stecker-Pinbelegung-AT-Keyboard.svg | XT connector's pinout                                        |\n| schematics/ps2-pcb.svg                             | PS/2 connector's pinout                                      |\n| ps2-to-xt-adapter.ino                              | Code for the actual protocol conversion                      |\n| ScanCodeMapping.tsv                                | Tab-separated file containg the scan code mapping from XT to PS/2.
