  Hans,
 I think the "cut-away drawing of the space shuttle" was a demo .dxf
 file that came with AutoCad. 
Thanks for the pointer. Searching for DXF on the web throws up a bunch
of possible stuff. Now to figure out how to plot DXF files cheaply!
I think the shuttel picture goes back further than that. Tektronix used
it extensivly in their promotions of the 40xx series, that would be late
70's
