An 8088/8086 Assembler
This is a DOS based assembler which I wrote in 1989. It supports the full 8088/86 instruction
set and works on more recent processors too. As well as a command-line assembler,
there is an editor with hot-keys to assemble and test your programs.

Note that this program will not run on 64-bit Windows 7 because this operating system does not
support 16-bit DOS programs. However, it will run on 32-bit Windows 7.
