I sent this to Edward, who asked me to repost it here.  It's about screen 
shots of the old ancestor to GF4, still running in a DOSBOX virtual DOS 
machine.  As a reminder, back then DOS graphics mode had a resolution of 
320 X 200 pixels across the screen.

 "Just for laughs, here is a screen shot of the old version running in 
DOSBOX.  It's called "gstat" here instead of "gf2" because I had two 
versions with a somewhat different but overlapping set of functions in 
each.  Gstat had curve smoothing, gf2 had the FFT routine. By "old" I'm 
talking circa 1990. 

Notice the noisy damped sine wave, just like we created in our Zoom tour of 
gf4.  The gf2 screen shot shows a log-log view of the FFT of the damped 
sine wave, again just as we did in our tour. 

Back then I didn't have the button window.  All functions except the curve 
generators were dispatched from menus, most with keyboard accelerators.  I 
couldn't afford the screen real estate for a button window! - although my 
windows manager would have had no trouble supporting one.  The curve 
generation panel could be disappeared to make more room for the curve. 

As I mentioned during our tour, the upper and lower scale labels on the 
vertical axis were actually calculator boxes if clicked on. Gf4 doesn't 
have that! The label "random noise" was generated by the program and would 
become the file name if the curve were saved.  The label is a clickable 
single-line edit box. 

All graphics elements on the screen except for graphics primitives were 
provided by my windows manager.  The font was an 8 X 8 pixel fixed width 
font provided by the TurboPascal graphics package. 

The half-tone effect in the background was a texture provided by the 
TurboPascal graphics package.  I found I liked it a lot and made it the 
default, though it seems unconventional today (I still like it, though). 

Not gf4, but a recognizable ancestor. "
