"Commodore BASIC" (cbmbasic) is a 100% compatible version of Commodore's version of Microsoft BASIC 6502 as found on the Commodore 64. You can use it in interactive mode or pass a BASIC file as a command line parameter.
This source does not emulate 6502 code; all code is completely native. On a 1 GHz CPU you get about 1000x speed compared to a 1 MHz 6502.
Of course it runs NetBSD.

There is even a portable Windows version that doesn't require installation.
libSodium is an implementation of DJB's crypto library NaCl which is actually portable - it'll run on many different operating systems (not just a few Unices), it supports parallel processing, and includes all of the conservatively safe crypto primitives that you've come to expect from the original. Optimization and benchmarks are performed at compile time for your platform for maximum portability. Includes bindings for several different languages that NaCl doesn't.
