There are 4 options for ordering software upgrades from Midon Design.

1. Download the object (hex) code and program the 68HC908KX8 processor yourself.  This will require the use of a stand-alone programmer.  TEMP08 does not support in-circuit programming.  There is no charge for this option.
2. Order a new processor chip with the new software.
3. Order a replacement processor chip with the new software.  You will initially be charged for the new chip at full price but 50% of the order amount will be credited to your PayPal account upon our receipt of the old chip, less the initial shipping charge.
4. Order a replacement processor chip with the new software.  You will initially be charged for the new chip at full price but you will receive a credit of 50% of the purchase price applicable towards future Midon Design orders upon our receipt of the old chip, less the initial shipping charge.

1. Remove power from the TEMP08!

2. Using a small screw-driver, or similar tool, gently remove U1, the 68HC908KX8 micro-controller, by inserting the screw-driver between the micro-controller and the DIP socket that it is inserted to.

3. Making sure that you are grounded, or adequately static free, insert the new micro-controller into the socket.  Care should be taken to observe correct polarity.  The end of the micro-controller with a small notch, or a dot in the left-corner, should be positioned to be close to the J1 connector as per the diagram above.

4. Make sure that all micro-controller pins are seated in the socket.  Check for pins that may have bent inwards.
5. Restore power to TEMP08.
6. Enjoy your new features.
