7-2-1 Saving Program Memory Data
1, 2, 3... 1.
254
Both Program Memory (UM) and DM area data can be backed-up on a stan-
dard, commercially available cassette tape recorder. Any dependable mag-
netic cassette tape of adequate length will suffice. To save a 8K-word pro-
gram, the tape must be about 15 minutes long (about 2 min. per K word of
data). Always allow for about 5 seconds of blank leader tape before the
taped data begins. Store only one program or section of DM area on a single
side of a tape; there is no way to identify separate programs or DM areas
stored on the same side of the tape.
Note UM and DM can be recorded together in a single cassette if the file number
of the UM is different from that of the DM and also if the capacity of the cas-
sette permits.
Be sure to clearly label all cassette tapes.
Use patch cords to connect the cassette recorder earphone (or LINE-OUT)
jack to the Programming Console EAR jack and the cassette recorder micro-
phone (or LINE-IN) jack to the Programming Console MIC jack. Set the cas-
sette recorder volume and frequency equalizer controls to maximum levels.
The PC must be in PROGRAM mode for all cassette tape operations.
While the operation is in progress, the cursor will blink and the block count
will be incremented on the display.
Cassette tape operations may be halted at any time by pressing CLR.
The following error messages may appear during cassette tape operations.
File number on cassette and designated file number are
not the same. Repeat the operation using the correct file number.
Cassette tape contents differs from that in the PC. Check content
of tape and/or the PC.
Cassette tape is faulty. Replace it with another.
This operation is used to copy the content of Program Memory to a cassette
tape. The procedure is as follows:
Press EXT and the 0 key to specify Program Memory.
2. Input a file number for the data that is to be saved.
3. Specify the start and stop addresses of the section of Program Memory
that is to be recorded. When the start address is designated, the default
stop address will indicate the last address of the Program Memory. De-
termine the address of END (01) and designate this address as the stop
address. Do not designate a stop address greater than this one.
4. Start cassette tape recording. Use only reliable, high quality data use
tapes.
5. Within 5 seconds, press SHIFT and REC/RESET.
Program saving continues until END(01) or the stop address is reached. At
that time the program size in Kwords is displayed. If the END(01) is reached
before the stop address, the recording operation will continue, however,
through the designated stop address unless CLR is pressed to cancel.
