DISKETTE/CASSETIE OPERA TlONS
Transfer Programs Between Cassettes and Diskettes
To transfer programs between cassettes and diskettes, load the
program into the computer's memory using the OLD command.
Then save the program using SAVE.
For example, the following sequence transfers a program from a
cassette to the diskette in Disk Drive One ond assigns BRYAN as
the program file name.
OLD CS1
(follow normal cassette instructions)
SAVE DISK1.BRYAN
The data is now on the diskette in Drive One under the name
"BRYAN".

The following sequence transfers a program named "EDGIN" from
the diskette in Disk Drive One to a cassette.
OLD DSK1.EDGIN
SAVE CS1
(follow normal cassette instructions)
The program is now on the cassette.
Transfer Data trom Cassette to Diskette
T o transfer data from a cassette to
a
diskette, you must read i t from
the cassette into the computer and then store it on the diskette.
You should first decide how you are going to store the data o n the
diskette, that is, what parameters you are going to use in the OPEN
statement.
The following program transfers data from a cassette to a file na-
med KAY on Disk Drive One. The file is set up in default format.
1 00 OPEN
*
50:CS 1 "
11 O OPEN-:f. 50:DSK1.KAY"
120 READ-:f. 50:X$
130 REM WHEN THE FILE ENDS, THE
PROGRAMM WILL HAVE AN ERROR
140 PRINT-:f. 60:X$
150 GOTO 120
When you run the program, you will be instructed how to use the
cassette.
The EOF function cannot be used with cassettes. After you run the
program, it ends with error 33, because the cassette runs out of
data. YOU MUST LEAVE BASIC BY ENTERING "BYE". lf you leave
with (QUin, data may be lost from the diskette.
SERVICE INFORMATIONS
IN CASE OF DIFRCUL TlES
lf the disk system does not appear to be working properly, check
the following:
1. Power- Be su re ali devices are plugged in. Then turno n the po-
wer to the units in the proper sequence: disk drives and Expan-
sion Chassis first, followed by the console and the monitor.
2. Card Position- Be sure that the light you are checking corre-
sponds to the position of the card.
3. Light Malfunction- lf you think one of the lights may be burned
out, insert the card in another slot.
4. Connector Separation - Check for proper alignment of the
console and the controller.
5. Cable- Check that the proper cables are being used. Check
the cables for loose or broken leads. Check to see that the ca-
bi es are properly connected, right side up.
6. Software- Be su re ali commands and statements are used as
described in this manual. lf the disk system works properly with
the Disk Manager Command Module but not with a program, the
problem is probably with the program. Especially check the use
of OPEN, INPUT, and PRINT.
7. Diagnostic Tests- Check that the diskette, controller, and disk
drives are working properly by running the diagnostic test.
8. Expansion Chassis - Check for proper connection between
the console and chassis unit.
9. lf none of the above procedures corrects the difficulty, consult
"lf You Have Questions or Need Assistance" or see the "Servi ce
lnformation" portion of the User's Reference Guide.
