and to stay in our favorite languange here
any "mini" system like raspbery (or this one ?) who runs linx with decent browser (firefox/chromium) can run
SpiderBasic programs
which i believe (hope ?

) its, along with PB, favorite syntax here
to discuss about your topic also, RaspberryPi is preferred because its much more widespread / more versions / cheaper versions
can also run Android (again Spiderbasic with apk created projects should work i guess)
and for Basic, its not dead at all
its the second most widespread language (after C++ offcourse) among all OS's and embedded systems
and its spead by the most significant factor depends on compiler
for example PureBasic, a true Basic compiler, will ALWAYS be faster than MMBasic (your link has this basic for interpreted) because iti is an interpreter
also the coder makes the difference, for example ANY code I will EVER wrote in C/assembly PB will be ALWAYS, slower than Fred's code in PB.... brain optimization and knowledge makes the biggest difference here
