+# Default keymap for m122-3270
+
+This keymap is intended to make the PC/3270 122-key IBM keyboard work as closely as possible to the standard
+PC/3270 keyboard's (part number 1397000) original mapping. Two layers are defined: layer 0 is the PC layout,
+using the blue legends on the PC/3270 keys (as shipped by Unicomp; I don't have the original keycaps, and I
+know there are a few differences), while layer 1 is the 3270 layout, with keycodes selected to make the `x3270`
+suite do the right thing with each key as pressed. The idea here is, eventually, to get `x3270` to
+automatically shift the keyboard to layer 1 when it gains focus.
+
+When layer 0 is active, the upper left key of the 10-key pad is Escape, the Reset and Enter keys are Control, and
+the comma and dot keys act like normal PC keys (< and >, repectively, when shifted). The Ctrl key (bottom right
+of the left-side 10-key cluster) is always the left GUI key. PA2 and Jump/PA3 are PgUp and PgDn, respectively,
+and the backtab key is End. The Rule/Home key is Home. The key next to the Escape key is Scroll Lock when unshifted,
+and Num Lock when shifted.
+
+When layer 1 is active, the keys do their labeled functions. The only keys that don't do anything are CrSel,
+ExSel, and Jump, though only a few of the alternate functions (on the front of the keys) work: left/right/delete
+word and PA3. The rest aren't emulated by x3270. Many of the keys that have function in PC mode will *not* have
+that same function in 3270 mode, since x3270 uses different keystrokes to accomplish the same function.
+
+To manually switch to layer 1, hold the Zoom key (the one on the far lower left of the keyboard) and press Clear
+(the one at the top right of that same block of 10 keys); to switch back to layer 0, hold the Zoom key and hit
+Attn (the one at the top left of that block of 10). Holding the Zoom key and the spacebar gets you to keys that
+control QMK itself: Zoom-space-R resets to the bootloader, Zoom-space-E erases the EEPROM (which currently does
+nothing), and Zoom-space-D turns the debugger on and off.
+
+Note that you need to set your Linux system to use the Scroll Lock key as the Compose key in order to get the
+cent sign to register as intended, and add the following lines to a file in your home directory named `.x3270pro`
+to make Dup and Field Mark work:
+```
+x3270.keymap.m122: #override \
+ Ctrl<Key>F: FieldMark()\n\
+ Ctrl<Key>D: Dup()
+```
+You need to then invoke `x3270` with the parameter `-keymap m122` to activate those definitions.

+![IBM Model M 122 key](https://i.imgur.com/Oo3Ozqzh.jpg)
+
+This is a replacement controller for the IBM Model M 122 key terminal keyboard
+running on a STM32F411 BlackPill, intended to act as closely to the 3270
+keyboard's functioning as possible while still being usable on a PC.
+
+* Keyboard Maintainer: [Jay Maynard](https://github.com/jmaynard)
+* Hardware Supported: BlackPill STM32F411, Teensy++ 2.0
+* Hardware Availability: [BlackPill](https://www.adafruit.com/product/4877), [Teensy](https://www.pjrc.com/store/teensypp.html)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make ibm/model_m_122/m122_3270/blackpill:default
+    make ibm/model_m_122/m122_3270/bluepill:default
+    make ibm/model_m_122/m122_3270/teensy: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).
+
+A schematic and Gerber files are publicly available for those wishing to have
+carrier boards made professionally instead of handwiring things. The M122
+matrix connectors plug right into it. It can be found at
+https://github.com/jmaynard/tronguylabs-m122-blackpill.
+
+This is derived from Luke Stanley's handwired/ibm122m keyboard, with my own
+keymapping and rework of the I/O for the BlackPill. There's also a version for
+the Teensy++ 2.0, since that was my original design and I still use one on one
+board, even though I switched to the BlackPill for future-proofing.
+The Teensy++ 2.0 is not recommended for new designs.
