Move the assembler to src/qasm. qlink links OMF 1.0 and 2.0 from a script. makeBin flattens a load file, qomf dumps OMF, and qpro builds ProDOS volumes. APW and MPW assemble through the ORCA front end. Relocatable modules emit OMF objects. Listings stay off unless -l is set. make boot assembles the GS/OS 6.0.1 ProDOS 8 kernel and BASIC.SYSTEM into an 800K volume. BASIC.SYSTEM accepts ls and pfx, and its splash reports PRODOS BASIC 2.0, copyright 1983-2026. IIGS.601.SRC is the source and the BASIC.SYSTEM oracle that image is built from.
