My first computer programming lab (pascal) used a VAX, for a lot of
people. We were so many that on the busy times (like when everybody was
compiling/testing their programs) we had to wait several seconds for the
cursor to move. I had to edit by counting letters and pressing the
keyboard blind. Oh, I thought it was so slow!
By that time I got my first PC, an 8086 (not 8088), 512K, 8MHz, no HD. I
could program my "exercises" at home (tpascal-2), without time limits. I
thought it was fast.
We did a program to recursively calculate the colors for a map, using four
colours only (there is a theorem that proves that only 4 colours are
needed for painting any map. I timed the program on the PC, and later in
the VAX. The surprise came when the VAX proved to be much faster, the
moment it was my program turn to run.
