Wheelwriter 5 (ISO Enter, boltmodded).

About
One of the more odd M variants, Wheelwriter keyboards are found exclusively on typewriters. Stock ones usually follow an M-like physical layout while having a non-M electrical layout. They also seem to have the same quirk of being able to substitute the reverse-L enter for an ISO enter.
While the SSK and other small form-factor buckling spring boards are "physically complete", one will have to harvest parts from the corresponding Wheelwriter. This is due to the Wheelwriter's keyboard being integrated with the typewriter as a part of a whole unit. Despite this shortcoming, Wheelwriter keyboards can be made into viable space-saving keyboards.
Why not attach it to an M controller?:
While it has a similar layout as far as having two M-like strips, the layout does not map to an M in any meaningful way. However, custom controllers like Soarer's can handle the layout - the only difficulty is sourcing a proper connector without harvesting an M(or two) for it. They do not interface directly with breadboards, but will fit snugly in flat sockets.
Once that is out the way, the keyboard can be attached.
Attaching the keyboard
This keyboard has the following mapping and layout:
(Note: Due to the lack of Wheelwriter keycaps, this one uses a mix of Terminal M, M, and M13 caps. I would be interested in finding a proper set, though.)
Block to use for Soarer's Controller:
To Do:
Source Wheelwriter 5 keys, and keyboard frame to assemble as a whole unit.
Thanks go to:
Phoenix from the other keyboard forum, for sending me the parts for a Wheelwriter 5 (and a matrix + plate from a Wheelwriter 3500).

#
# Wheelwriter 5 Matrix (ISO Enter)
# A sane, yet minimalist layout.
#
# Layout Notes:
# Layout mostly follows AT(Ctrl between Tab/Left Shift, Caps Lock below Right Shift) aside from ISO Enter/F11/F12.
#
# Top two keys in the 5-key vertical block are PgUp/PgDn respectively.
# Bottom two keys in the 5-key vertical block are F11/F12 respectively.
#
# The middle key in the 5-key vertical block on the right can be used as follows:
# [Modifier]-WASD : Cursor keys (Up/Left/Down/Right)
# [Modifier]-[Number key] : Equivalent numpad key
# [Modifier]-[Backspace] : Del (for those wishing to perform Ctrl-Alt-Del, use Ctrl-Alt-Modifier-Backspace)
# [Modifier]-[PgDn] : Left Win/GUI key
# [Modifier]-[`] : Escape key
