Editing Converter (section)

==DIY converters==
It is possible to make a custom converter using a small microcontroller. These converters have a few benefits in that they allow to transform the input and output, e.g. to make your own macro keys or Fn layer.

The easiest way is to use a development board with an Atmel controller like the [[Teensy]] board for example.

===Soarer's XT/AT/PS2 converter===
{{main|Soarer's Converter}}

A general-purpose converter with handy tools to customize the keymapping of the provided binary file. Only the source of the tools is available. The documentation can be found on [https://geekhack.org/index.php?topic=17458.0 Geekhack]. See [https://deskthority.net/workshop-f7/xt-at-ps2-terminal-to-usb-converter-with-nkro-t2510.html this forum thread on DT] for more info.

'''NOTE''': a [[Teensy]] should be sufficient for the firmware and some basic config files. If you want to do a lot of advanced stuff like macros and Fn layers, try the the Teensy++. Check the documentation for more info.

===Hasu's USB Controller/converter projects===
{{main|TMK}}

These projects are only available as source code on [https://github.com/tmk/tmk_keyboard GitHub]. It is specially written for the [[Teensy]] development boards and keymapping must be done in the source files themselves.

A short overview of sub-projects:

*Macintosh ADB to USB converter ([http://geekhack.org/showwiki.php?title=Island:14290 documentation on Geekhack])
*PS/2 to USB converter ([http://geekhack.org/showwiki.php?title=Island:14618 documentation on Geekhack])
*A converter for IBM terminal keyboards

===HaaTa's Kiibohd Controller/converter projects===
{{main|Kiibohd controller}}

Only available as source code on [https://github.com/kiibohd/controller GitHub]. It has a number of modules that can be re-compiled to support various obscure keyboard protocols. Designed to work as a converter or as a replacement controller depending on how the configurations are setup. Keyboard layouts and macros are configured on their one layer independent of the input scan module and output module. The framework is designed to support multiple output protocols, but currently only a basic 6KRO USB module is working.

Current list of supported protocols:

*Burroughs [[BET-KB]], ET2120 Computer System
*Epson QX-10 Computer Keyboard ([[Epson Q703C-AA]])
*[[Kaypro 1 Keyboard]]
*CTOS keyboard ([[Convergent 64-00164]])
*Sony NEWS keyboard ([[Sony NEWS NWP-411A]], [[Sony NEWS NWP-5461]])
*[[Tandy 1000]] keyboard
*[[Univac F3W9]] keyboard
*Matrix Mode (Controller Replacement)
**[[Bud 83959|Bud Hall Effect Keypad]]
**Heath Zenith [[Alps 12KC132A]] keyboard
