GENERAL------------------------------------
The Cassette Tape Loader (15735140-001) is used to dump, load, and wrify the data file of a DELTA 21 System. The
data file can be entered into the system on-site vi;i the Video Display Terminal (see DELTA 21 Programmer's Manual,
Form No. 85-0097).
It
may be easier, however, to load the data lile with the Cassette Tape Loader (tape loader) after
having programmed it at the branch.
For its three operations, the tape loader is connected to the I/O board of the Energy Control Unit (ECU). An operator

to
arrive at the Cassette Operations menu. From this
menu, a Level 3 operator can select dump, load, or verify operations.
Tape loader software controls all tape loader functions except Initialize.
