do you know how this may have happend ans/or how to fix it?

LOAD (with no filename following) is the command to load a BASIC file.

LOAD does not require parameters, but it loads *two* recorded segments
from tape, the first is quite short and specifies the length of the
second segment, which contains the BASIC program.

Since you typed LOAD <RETURN> and no recorded audio data was detected,
you got one ERR beep when the first segment was missing, and a second
ERR beep when the second segment was missing.  This is normal when no
audio data is present at the cassette input of the computer.

SAVE saves the current BASIC program in two audio segments--the first
contains the length of the program and the second is the program itself.

When loading or saving to cassette, the cassette should be started prior
to pressing RETURN to execute the load or save command.  In the case of
loads, ideally the cassette recorder will be playing back the several
second "preface" tone when RETURN is pressed.


Looks like your right.

I have set up two apple machines,
connecting the cassette out port of one machine, to the cassette in port of the second machine.
And also vice versa.
no ERRs at all, yet, LOAD seems to hang.
<does load take any parameters, or may my cable be defect, or the
cassette port defect, or does the load procedure take a long time after
the SAVE command is trough>

Unfortunately, that won't work--unless you loop each cassette out
through a cassette recorder in "monitor" mode--since the cassette
out is at "microphone" level and the cassette in is at "speaker"
level.

LOAD therefore hangs because it never sees ("hears"?) a tone at all.

You'll need a cassette recorder and a cassette to record a program
and play it back into the other machine, or two cassette recorders
in monitor mode to hook two machines directly together.
