I just released a Python-based interpreter for the CESIL language.
When I was first being taught computers (1983-1985), this was our first language. It had a massive total of 14 instructions and initially ran as a batch job. In my school, we had a Research Machines thing that ran the code but getting access was hard.
It was a good experience though. I was taught to plan properly: Write the expected output for a set of inputs (unit testing on paper), draw a flowchart of the flow, and then write the actual code on paper before even sitting down at a computer.
More information on CESIL.
BTW, I got Salstat running on FreeBSD as well as Linux, OSX and Windows.
