WRITE OPERATIONS
Other than placing the recorder in the record mode, loading
the tape and making sure that the head is on tape (not leader), no
manual operations are needed to write on tape.
4.6
READ OPERATIONS
When reading tapes, you must start the tape at least two sec-
onds ahead of the data block you want to read.
(CUTS tapes have a
standardized header before each data block.)
This two second delay
is needed to allow the recorder playback electronics and the CUTS
circuitry to stabilize after power is turned on.
Use the following procedure for loading tapes:
1.
Disconnect monitor and remote plugs from recorder.
(On
most recorders this must be done in order to listen to
. the tape.)
2.
Load prerecorded cassette and play tape until you hear
data.
(Data sounds like noise in CUTS format.)
Absence of data is indicated by a pure
1200 Hz or 2400 Hz tone if recorded at
1200 bps or 300 bps respectively in the
Byte/Kansas City Standard format.
3.
Rewind tape far enough so it will take two seconds to
reach the data block you want to read after the recorder
is placed in the playback mode.
STOP RECORDER AT THIS
POINT.
4.
Set Volume Control as specified in Paragraph 4.4.1 if
necessary.
5.
Reconnect monitor and remote plugs to recorder.
6.
Place "play" control on recorder in play position.
7.
Type in appropriate command on your keyboard.
After you
strike the RETURN key (in most programs), the recorder
will automatically start and data will be read into mem-
ory at the locations specified by the CUTS data header
or, in the case of BASIC-5 or Processor Technology 8K
BASIC, into the proper File or READ statement.
