SE Basic IV

SE Basic IV is a free open-source BASIC interpreter for the Z80 architecture. Although it aims for a high degree of compatibility with Microsoft BASIC, there are some differences. SE Basic IV is designed to run on the Chloe 280SE but it is also compatible with Timex Sinclair models with 128K of RAM, esxDOS, Timex video modes and ULAplus. SE Basic IV runs plain text .BAS files. It implements floating-point arithmetic in the extended Microsoft Binary Format (MBF) and can therefore read and write binary data files created by 6502 versions of Microsoft BASIC.
