General Information
Many standard cassette recorders can be used
with the computer, For best operation, however.
they should have such features as:
• Volume control
• Tone control
•
Microphone jack
• Remote jack
• Earphone or external speaker jack
• Digital tape counter (This will enable you to
easily locate
the correct tape position in case
you want to store more than one program or
data set on the same tape,}
Since motor control design V:lrjps from
manufacturer to manufacturer, we have tested
several different cassette recorders to determine
whether they can be used with the ('.nmpl1tF.f. A
list of recorders that appear to work well with
this computer is included separately. We've also
indicated the volume setting and tone control
setting for each unit that give the best operating
results.
Texas Instruments can assume no responsibility
for
any design changes made by the cassette
recorder manufacturers that might affect the use
of a specific recorder with the TI computer.
Carefully follow the directions for setting up and
using yUU! recorder, as described in the
remainder of this section, If your cassette
recorder does not appear to be compatible with
the
computer, try cJ.i~culllleclillg, the black wire
from the remote jack on the recorder and
operating the recorder manually. If you can save
or load data while operating the recmder
manually, but cannot do so when the black wire
is connected, you
may continue to operate the
recorder manually or change to one of the
recommended cassette units.
