| AS31
is a free 8051 assembler originally written by
Ken Stauffer.
Versions of AS31 found here include important bug fixes and added
features, such as standard intel-hex output format for use with PAULMON2
and EPROM programmers. AS31 is a good tool for building small 8051-based
projects that are written in 100% 8051 assembly language.
