Altronics PerformAire Eclipse Weather Station Air Quality Computer System.

Selling for Parts.  Does power on.  Needs Firmware update. 

Eclipse Unit with an RJ11 port.  Purchased from a fellow racer knowing battery was low.  At the time all functions worked when plugged in.  

Attempted to replace battery (old and new included).  Evidently the old data somehow cleared during the procedure.  

When plugging in the message reads:  Firmware Update:  waiting.

Physically everything is in very good to excellent shape.   Perhaps you can fix or figure out how to flash the firmware.  Evidently they used to sell a kit for DIY.  Unfortunately, no longer available.  

Just sitting in my garage.  So hopefully someone can make some use of it.
