Assembly Libraries for 8-bt GEOS operating system
Dozens of self contained internally consistent libraries for programming in assembly on Commodore 8-bit GEOS operating systems and compatibles. See the README for details on the libraries and their APIs.
Specter - Abstract Arithmetics Library (AAL) is a library coded in native C which is able to do operations with numbers of virtually unlimited length. Specter is targeting mainly cryptography and big integer maths though.
