MACTAP is a set of PDP-6 subroutines to read and write DECtape in the MAC file format (see MAC-M-249). Programmers can call these subroutines for input or output of ASCII data, which will be compatible with TECO files; or for binary (36. -bit word) data. They were extracted mainly from PDP-6 TECO and arranged and checked out in their present form by Jack Holloway.
