Not exactly true. One correction to my own post, the magazine was "Unix
Today" not "Unix Week".
The origional poster (whose name I no longer can recall, sorry) asked
about 3b1 X-Server aplications (ie a windows manager etc...). The responce
I posted was a reaction to this.
I have used MacX on our computers here at 'SC, but you must remember
that MacX runs the X-App on the _Unix_ box and just gives the graphics output
on the Macs screen. In this case your 1-2MB on disk and 2MB RAM are completely
slaved to supporting monochrome graphics SLOWLY. Not the best solution.
Perhaps some way of doing something similar on the 3b1 could be
concidered. Remember, though, that the 3b1 monitor is not huge (720x350ish).
Recomended screen size for an X terminal is 1 megapixel. Might be an
interesting project though...
