Steps to Save to Cassette (CoCo 1, 2, or 3):

Connections: Ensure the cassette recorder is connected to the back of the CoCo 
using the 5-pin DIN cable. 

Issue Command: At the OK prompt, type CSAVE "FILENAME" and press ENTER.

Wait: The screen will go black while saving. 
The computer will return to the OK prompt when the saving is complete.

Verify: It is recommended to press STOP, rewind the tape, and use CLOAD "FILENAME" 
to verify the program was saved correctly. 

Important Notes:

Filename: Use a simple filename, up to 8 characters.

Volume: If you have trouble saving or loading, adjust the volume level 
(usually moderate or low is best).
