I guess somewhat related but are there any people on here who're programming / are interested in programmer 'classic' 8-bit machines? If so, are you using assembler or are you using C? (SDCC comes to mind. Not the greatest at code generation, but hey.. )
If you count TI calculators (TI 83 plus mostly) as 'classic' then yes. I use mostly assembler, but z88dk has proved very useful for playing. I also make frequent use of various interpreted languages like Forth and Basic for making things quickly.
