+
+[IBM 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 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
