WIlli Kuche has documented the Merlin Macro Assembler IDE Source code and made it available for download. Merlin, which was written by Glen Bredon at Southwestern Data Systems, was available for download for the past two years, however, the version that was available was without documentation and without instructions for building the IDE.
Now after a long effort by Willi, the IDE is documented, and according to Willi’s note left on CSA2, “it contains all the source files needed to generate version 2.59, but no others, plus step by step instructions to assemble the four primary source files, to bind together the four generated object files and to compare the newly generated “MERLIN.SYSTEM” against the original. “
You can download the complete source code for Version 2.59 of the 8-Bit version of Merlin at:
