Let's Make a C64 in BlitzMax_NG 

Baggey

For those that cannot be bothered to learn Z80 machine code on the Sinclair ZX Spectrum. There is Boriel BASIC.

Don't forget Dunny's SpecBas as well. Just saying "LIKE".

I'm sure that ZXDunny's SpecBas is just a modified basic PC OS interpreter.  Boriel BASIC is a full compiler for the ZX Spectrum written in Python, with a syntax and command set as close to ZX Basic as possible.

Speaking of compiler and assembler. There's also sjasmplus.

And if you like PASCAL. There's Turbo Rascal Syntax Error. Note that this supports a number systems to a varying degree.
