MSA is an x86 assembler that supports all 8086 instructions and most of the 80186/80286 instructions. MSA outputs flat binary output (.COM) files. Robert Ostling has released his MSA assembler as open source software, under the MIT license. Robert wrote MSA in C, using Borland C++ 2.0, but thinks it will not be hard to port to other compilers.
