Abstract: MTFOTP (Mag-Tape File-Oriented-Transfer-Program) is a

modification of DEC's FOTP which treats magnetic tape as a special

directory device while at the same time retaining other FOTP functions.

It can thus be used as FOTP.SV with extended mag-tape functions. These

include (I) directory I/O, (2) positioning, and (3) subfile directories for

grouping files.

TM8EZ is a handler written for the TM8E controller equipped with 9-

track TU-10 magnetic tape. Using the DEC supplied handler, it is

impossible to read or write industry compatible 9-track tape from

standard OS/8 buffers. TM8EZ and the extended handler TM8ESU

decode OS/8 buffers and read/write in standard 9-track mode, 384

characters/record (variable length records optional) with one ASCII

character per frame. TM8EZ is ideal for use with MTFOTP when data

must be transferred to other magtape equipped computers.
