rawtap Allows extract, create and append operations on .tap files. cpytap Copies a .tap file to a new .tap file while allowing file level edits; skip file, replace file, append files and insert files. Any files copied from the original source .tap will have their internal record structure maintained. cosy COSY is the compressed format used by the CDC1700. This program allows for extraction of all files from an archive and the creation of a new archive. It assumes that you would have used raw tap about to have extracted the COSY file from a tape. dbtap Utility to read, write and list .tap containers written in the DOS/BATCH-11 format. It understands ascii and binary modes and can be used to transfer files in and out of most PDP-11 operating systems (not sure about RSTS/E), early VMS and early TOPS-10 systems.
