====== Backing up patterns/dumping memory from kh930e to computer ======
Start up the disk drive emulator in the command line by typing in **python PDDemulate-1.0.py img COMPORT** where **COMPORT** is your serial connection. For example on a mac the command might be **python PDDemulate-1.0.py img /dev/tty.usbserial-A7TKMHYD** this will make an 'image' of the knitting memory in a directory called **img**

Now on your machine...

  * When "ready" lamp is lit, clear display with **CE** key, then prepare to save pattern data to "disk" by typing **552**, then **STEP**.
  * Display will go blank and then "ready" and "pattern no" lamps will light up with the "track" number 1 in the display. Press **STEP**.
  * Machine will beep when finished, and the track data will now be in the **img** folder along with your emulator and other scripts.
  * The emulator also makes a handy **file-01.dat** file to make it easy to preview the patterns using **dumppattern.py**

We'll need that **file-01.dat** file, so make a backup of it somewhere else for safekeeping! That file contains all your patterns.
