With my first Commodore 64 back in 1984, I started with a 1541 (never 
had a datasette)... but it took three months because of high demand 
until the floppy drive could be delivered!

I gave my original Commodore 64 away in 1990 because I needed a "real" 
computer (i. e. an Atari 1040 STFM) for doing papers at university... 
but every few years I once more caught the C 64 bug, so I had to re-buy 
some used "breadbins"... my current one I bought together with a 1541 
for ten euros, but I had to take a 50-mile bicycle ride to get the hardware!

At 8-bit grayscale or at 16-bit vertical resolution? I recently wrote a 
PoV-Ray script that generates 16-bit heightfields (and, after this, also 
curved mesh2s) from SRTM Earth altimetry data processed with 3DEM (a 
geographical visualization software)... if I remember correctly, 3DEM is 
also able to process ASCII terrain matrizes from MOLA Mars (Mars Global 
Surveyor) topography data!

And since a few years, there are also topographical contour maps of Mars 
at 1:250,000 available...

Won't you like to post some of these images on p.b.i.?

See you in Khyberspace!
