Hello
I'm the author of Blassic, a Basic intepreter 8 bit era style.
https://blassic.net/I have a raspberry pi binary available for download, compiling it native takes some time and requires several dev packages.
It works on raspbian 32 bits. It may work in 64 bits, but its low level features (peek/poke, usr...) will probably fail because the integer type is 32 bits and addresses may be out of its range. You can configure it to 32 bits, but I have only tested that way on amd64, not in arm.
Enjoy.
