All the "current" programming specifications are here. http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1407 Some of the older one has the "gray color" box. Example: 16F72 http://ww1.microchip.com/downloads/en/DeviceDoc/39588a.pdf Page 5: Note: Any programmer not meeting this require- ment may only be classified as a "proto- type" or "development" programmer, but not a "production quality" programmer. Another example: for OTP http://ww1.microchip.com/downloads/en/DeviceDoc/30557g.pdf Page 2. Note: Any programmer not meeting the program- mable VDD requirement and the verify at VDDMAX and VDDMIN requirement, may "development" programmer, but not a production programmer.
