> I've been asked about a quarter-inch tape standard from 1976, called ECMA-46

   0Bh X3.55-1982, X3.56-1986, ECMA-46, ISO 4057-1979

from the scsi spec..

There is a copy of X3.56-1977 hiding in the back of a quantex tape drive manual
that I scanned this morning.

This is one of the original 1/4" tape formats, for a drive with a fixed position
four-track head stack (the norm prior to what became the QIC11 moving head 4 track

The scan is here:

the spec is appendix A
