Programming Console Operations
Cassette Tape Operations
Operation/Description
Program Memory Save
This operation copies data from
the Program Memory to tape.
The file no. refers to an
identifying address for the
information within the tape. For
ease of information retrieval,
the file number and data
information should be written
clearly on the tape. File
numbers should not be used
more than once on one tape. If
only a part of the Program
Memory is to be stored, the
appropriate start and stop
addresses must be entered.
Due to limited memory capacity,
each C60 tape can only store
apporximately 16K words on
each side of the tape. When the
start address is entered, the
maximum stop address is set
as the default. Do not set a stop
address past this one. If you
wish to record past this address
the additional information will
need to be recorded either on
the flip side of the tape or on a
separate tape. After starting the
tape recorder, wait about 5
seconds before pressing
REC/RESET to allow the leader
tape to pass before the data
transmission starts.
Program Memory Restore
To read Program Memory data
which has been recorded on a
cassette tape, the keystrokes
are as given here. The file no.
should be the same as the one
entered when the data was
recorded. The read operation
will proceed from the specified
start address up to the end of
the tape, unless halted by a
CLR command. The instruction
must be completed before the
leader tape has been played,
i.e., before the data is reached
on the tape.
Program Memory Compare
The procedure to compare
Program Memory data on a
tape with the Program Memory
in the Program Memory area is
the same as that for reading it
(see above), except that after
starting the tape playback, VER
should be pressed instead of
SHIFT and PLAY/SET.
