The later version of the mechanical Symbolics Lisp Machine keyboard has not been in production for decades. They are rare and legendary for their exceptional build quality. They feature a special keyboard layout for use with the Genera operating system, for Lisp programming and for the Zmacs editor. There are unshifted parentheses, control is next to space and it has lots of shift keys (Hyper, Super, Meta, Symbol, ...). There are special keys to switch between programs, to operate the window system, the terminal, the debugger, the console, ... Now there is modern Keymacs (https://keymacs.com https://keymacs.com) replica with USB interface and serious over-engineering. The instagram post shows a new version with the original Symbolics-like keyboard legend.
