This is a cross assembler for the LINC computer, compatible with Mary Allen Wilke's LAP6.
There is a separate tool for managing LINCtape images in LAP6 format. It can list the index, and read or write manuscripts and binaries. Forensic support include seaching for index and listing unused blocks.
The original LAP6 was more than just an assembler; it was also a text editor and file system for magnetic tapes. It was essentially an integrated development environment and operating system for the LINC. It managed all this with only 1024 instructions in memory at a time.
