A New Tiny Basic for the 6502 #Programming #BASIC @drogon

Gordon Henderson was looking to code a new language for the 6502, but in the process found NIBL Short for National (As in National Semiconductor) Industrial BASIC Language. Gordon, liking it’s features, came up with GIBL for Gordons Interactive Basic Language).

As I was rewriting it, I actually thought that the old SC/MP was going to be much more code dense that the 6502 – turns out they’re about the same, although some operations seems easier on the SC/MP due to it having 16-bit pointer registers with a variety of auto increment/decrement modes. However, the 6502 version is currently at just under 3700 bytes of code and runs much faster than the SC/MP version (for many reasons, not just that the SC/MP has a bit-serial ALU).

There are a few demo programs for it including my new Mandelbrot implementation, but be aware – Tiny Basics are not known for their speed.

Well, Gordon’s Mandelbrot demo runs in a tidy 82 seconds, not bad for a 6502.
