> How does the experience compare with using Pharo Smalltalk today? Genera is a full operating system running directly on Lisp Machine hardware. A CPU which runs a stack machine. The network code goes down to the packets and the Ethernet card driver. > There are Common Lisp replacements for Emacs, CL window managers, and one or two Lisp Machine style GUI libraries (CLIM).

He tried to help LMI, but stopped soon. Symbolics, LMI and then TI developed a lot of more software. Much more. > I'm often struck by how many Lisp Machine features have been implemented on other systems (e.g. CLIM, versioned file systems) yet haven't gained many users. There must be stories here. Versioned file systems existed before and after Lisp Machines. For example DEC's VMS had a versioned file system. CLIM was the attempt to develop a portable standardized version of the GUI library of Symbolics. It failed to gain real traction: too different, not very polished, everybody had already a different GUI toolkit, ...
