+# IBM 5291 keyboard converter
+
+![5291](https://deskthority.net/wiki/IBM_Model_F#IBM_5291_Keyboard)
+
+A converter for the eponymous keyboard.
+
+Keyboard Maintainer: [Listofoptions](https://github.com/listofoptions)
+Hardware Supported: IBM 5291, Teensy 2.0
+
+Make example for this keyboard (after setting up your build environment):
+
+ make converter/ibm_5291:default
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+
+the pinout is as follows:
+
+IBM−5291−Cable to Pinhead−14

+9 | D3
+10| D4
+11| D5
+12| D6
+13| Strobe
+14| Out
+
+the pins on this connector are organized ![here](https://geekhack.org/index.php?action=dlattach;topic=48950.0;attach=36759;image)

+|11 | D6
+|12 | Strobe
+|13 | Out
+|14 | PE
+|15 | NC
+
+the above connector is actually numbered so it should be easier to determine
+where the needed connections are.
+
+to connect to the teensy, the following are pins are needed (if you should choose not set your own):
+* PB0 -> PB6 are connected to D0 -> D6
+* +5V is connected to the corresponding teensy pin
+* gnd is as well, only one of the gnd pins needs to be connected though.
+* strobe is connected to pin PD1
+* data is connected to PD0
+* PE does not need to be connected to anything, but it could also be connected to gnd
