System Tapes
System tapes for AOS/VS came with a standard layout per class of machine. Tapes can be created from a running system with the ‘‘SYSTAPE.CLI’’ macro found in the :SYSGEN directory. The tapes may have been differently organised for AOS/VS II (tbc).
For all types of machine the first files are standalone programs which may be executed directly from tape. File #7 is the big DUMP_II of the files required to run AOS/VS.
Depending upon media capacity, a second tape may also exist; it has the same layout, but file #7 contains the remaining AOS/VS files that couldn’t fit on the first tape.
