HOO! You had a awfully big disk!!
We even couldn't afford a DF32. I had a lucky colleague in another lab
who had one, that was fast!!. But 7 years later ('75) we got a PDP-11,
which was rather difficult as it was hexadecimal instead of octal (I
still calculate faster in octal than in hexadecimal!).
But we programmed a FFT (Fast Fourier Transform) in this 4 K (12-bit)
environment, using so-called rotating buffers of 256 words. And it was
reasonably fast on a 1 MHz processor. Current programs waste memory and
cycles in the millions and lean programs cannot be found. That 's the
price of progress and sloppy programmers (my opinion!).
But your problem didn't exist then. HTTP came into existence in 1992!
