When I run your program, I get an "invalidfont", not an "invalidaccess".
The reason it fails is simple, actually:  your "restore" gets rid of
the current font.  What you have done boils down to this:

	save
	/Times-Roman findfont 12 scalefont setfont
	restore
	0 0 moveto (text) show

Remember that "save" and "restore" also save and restore the graphics
state, and that includes the current font.  There is no current font in
the default graphics state, which is what you return to after the
"restore".

I hope this helps clear up the problem.
