As a kid, I got a TI-57 as a present from my cousin from abroad. It was
impossible to find those things in Spain, or they were very expensive,
and only in the capital city.

I programmed a sort of moon landing simulator there. Later, I got (via
my cousin again) a TI-58C - I think I was on high school:

Here, the simulator was improved to consider air resistance, gravity
change, centripetal force, fuel weight…
Later, I could use a ZX-81 at a friend’s place.

The student residence I was at got 3 of these:
Spectrum
They used B/W, big TVs as display, got second hand. If I recall, I did
part of the setting up and purchasing. The cable was on the other side
of the room - people did sometimes tread on them pulling the plug…
after half an hour of loading a flight simulator game from tapes.
Finally, I got my own first computer: an Amstrad PC, with a whopping 512
KB of RAM and TWO floppies!

But B/W, not as the photos. I still keep it. I /think/ it still works.
I used it to learn programming. The university lab had one VAX
computer shared by hundreds of students. I think we got 3 hours per
week, to learn Pascal. When too many people were compiling, and others
were editing, you had to blind type and wait perhaps 20" for the display
to respond.
I tried renting computer time at a place, but it was expensive… and
they used something called ms-dos 3 and turbo pascal 2, so different
from the vax… so finally I had to buy my own machine to learn myself.
Well, to be honest, I did not buy it: my father did.
The assignment we had to do was to find a solution to the four color map
(it can be demonstrated that any map can be coloured with just 4
colours; our job was to find combinations of such). My PC found the
first 3 solutions in seconds, but the 4th took half a minute or more.
I thought that the VAX would be slower, but it was not: it found that
4th solution in a mere second or two. That VAX was good, the problem was
getting a CPU time slot.
