It is possible that you may accidentally damage the tape which contains the BASIC interpreter. When
this happens, you cannot use the computer. To avoid this, make a copy of the BASIC interpreter.
After making the backup copy, store the original tape in a safe place and use the backup copy for
daily use.

interpreter into memory.
5) When the prompt (*) appears, replace the tape with the new one and enter the following monitor
command,

6) When ‘“ £RECORD.PLAY” is dislayed, press the button of the data recorder to write
the BASIC interpreter to the new tape.
7) When the prompt (*) appears, rewind the tape. Then, enter the following monitor command.

8) When ‘‘# PLAY” is displayed, press the button to verify the tape contents.
