 **This page covers the most popular protocols. It is not an exhaustive guide. For information on less common protocols, see [[https://docs.google.com/spreadsheets/d/1dkd6VJnsCM6dvpHQpI_mbHEKbwe3ZXtNJjaB9DTi4Xc/edit#gid=0|CoolPenguin's spreadsheet of all converters]].**
+A **converter** is a small device that sits inbetween your computer and a non-USB keyboard, allowing its output to be read as a standard USB human interface device. There are two types of converter, [[terminology:active_converter|active converters]] and [[terminology:passive_converter|passive converters]]. There are both commercial and DIY options available. It should be noted that commercial converters are often sold at a considerable markup compared to making one yourself, sometimes as much as 400% markup. In almost all cases, making a converter yourself is cheaper and more effective.
+==== AT, XT and PS/2 ====
+=== DIY converters ====
+=== Commercial converters ===
+=== Firmware ===
+There are a variety of firmwares available for active converters for these protocols. However, almost all of them have been superseded by purdeaandrei's excellent [[https://github.com/purdeaandrei/vial-qmk-with-ibmpc-usb-converter|QMK/Vial port of the TMK ibm_pc converter]]. A direct download of the firmware for Pro Micro based-converters is [[https://github.com/purdeaandrei/vial-qmk-with-ibmpc-usb-converter/releases/download/v0.0.6/converter_ibmpc_usb_atmega32u4_caterina_vial.hex|here]]. This firmware handles all Set 1, Set 2 and Set 3 protocols, as well as handling keyboards that use the reset line (if wired).
+This firmware allows for dynamic remapping, as well as all the other QMK features common to modern keyboards. You will typically see a lot of older content in the hobby talking about Soarer's converters - this firmware was last updated in 2014 and is now extremely outdated and incompatible with a number of edge case boards. **We recommend avoiding it**.
+==== ADB ====
+=== DIY converters ====
+=== Commercial converters ===
+===Firmware===
+Historically, the firmware used was the t.m.k. ADB converter firmware, though in recent years this was ported first to QMK, and then also to Vial. [[https://wiki.keyboard.institute/lib/exe/fetch.php?media=guides:adb.hex|A Vial port of the ADB converter firmware can be downloaded here]], which has support for all ADB keyboard layouts.
