Zmacs is just ONE application on it. Applications are not Zmacs buffer modes.
The shown applications, Listener and Peek are not Zmacs buffers or windows. Neither one uses Zmacs buffers/windows.
If you look at the Listener application window:
* it has no terminal mode
* it has no minibuffer
* it has no meta-x commands
* it is fully graphical (postscript compatible drawing model)
* you can't split it
* it has no menubar
* it has no iconbar
* it has no modes, it is just a Lisp listener and a command interpreter
* it is not an editor window and not an editor buffer,
you can't edit the text printed to it
* for each output it remembers the Lisp objects
* for each input it can reuse the Lisp objects
* since it is a window, you can resize/move it
* you can only type commands and s-expressions to it,
and they will be parsed online
Not sure of a good place to ask this but I've been wondering for a few years, so I'll try again in this thread. Does anyone know where to purchase a Symbolics machine in 2017? Is anyone here looking to sell their LispM?
I had to scan over that page a few time to put a date on it!
Seeing a price of $1100 for a IIfx was pretty disorienting, when I was shown the invoice to a IIfx system I was using back in about 92, that was in the region of 8 - 10,000 GBP.
I guess the depreciation from '92 through Y2K accounts for that. Similar depreciation accounts for the $900 price tag on the 32 GByte dual E5-2690 workstation under my desk...
