+# HP 46010A
+
+![46010A](https://deskthority.net/w/images/a/a5/HP_46010A_--_top.jpg)
+
+A converter for the eponymous keyboard.
+
+Keyboard Maintainer: [Listofoptions](https://github.com/listofoptions)  
+Hardware Supported: HP 46010A, Teensy 2.0  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make converter/HP_46010A: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).
+
+to get a matrix created if your board uses a different one (i used the US layout) please see the following gists:
+for the matrix itself: https://gist.github.com/listofoptions/cdf70d94767e9c6c027741850a24c568
+for the program to generate the matrix: https://gist.github.com/listofoptions/d245e370678024edbe5bed8c8ab17999
+
+to build the actual converter, you are going to need to either splice into the a connector or, use a multi-meter to buzz/ohm out which wires go where.
+from the bottom of the pcb the pins are arraged as follows:
+
+
+      4 5 6
+     3 2 1  
+
+
+connect a six pin modular connector of the 6p6c variaty.
+then lop off the other end of the cable, striping the wires inside.
+use the ohm-meter to find the corresponding wire for each pin on the bottom of the pcb
+
+the pin meanings are as follows:
+1 reset
+2 no connection
+3 vcc
+4 data out
+5 clock
+6 ground
+
+wire the ground and power pins to ground and 5v power on the teensy (or other avr device of your choice)
+connect
+on the teensy the connection is as follows
+
+
+teensy | HP 46010A
+----|-----
+gnd | gnd (6)
+vcc | vcc (3)
+PB0 | reset (1)
+PB1 | clock (5)
+PB3 | data out (4)
+gnd | no connection (2) -- optional
