(This page is from our original web site, and describes two proprietary products that are no longer offerred.  One describes an old 'engine' type computer (the Chargecard), which was used in many of our 8051-based designs in the assembly language era.  The other describes a full featured, custom-purposed system for remote data acquisition, control, and monitoring.  Several hundred of these systems were deployed nationwide, primarily in Lowe's hardware stores, to monitor their backup power generators.  Both are still useful, but far from leading-edge!)

Chestnut Ridge Technologies currently offers two proprietary electronic products:

The Outpost:          Remote monitoring and control computer

The ChargeCard:   Integrated microcontroller - 8051-compatible!
