Will Sleepyhead work with the above machine?
You need to visit the SleepyHead website where all the supported machines are listed. I've read on various forums that users had issues uploading the data to SleepyHead because the software wasn't fully supported for their machines, therefore, you need to identify the correct model and then check it against the supported ones.
