Boot-to-Basic Computers are great fun and excellent for learning but just do not have the stack to build real world applications in 2021 on eg SQL, sockets, SSL, etc
I would love to be able to just turn on the computer and have a simple basic program run a touchscreen interface to my factory SQL systems but we truly must stand on the shoulders of giants in this regard.
(talking about boot-to-basic here no basics that run on an OS and can access the whole OS stack)
Did a search to see if it has been done. Yes, there is an EFI Basic of sorts:
UEFI Basic
While there were several flavours of BASIC compilers there were never as widely spread as these interpreters.
I find it interesting, it could have been yet another what-if, had the compilers been as widely accessible.
