Good Day Charles,
You could get the Intel® System Studio for Microcontrollers from the below link:
This Intel® System Studio for Microcontrollers versions are compatible with the Intel Quark microcontroller D2000.
Thanks and Regards,

There is some sort of disconnect here, you need to put the link for the ISS for D2000 back if you are going to continue to sell the D2000's in the retail market. Or buy our D2000's back that we can not use. Nothing at Mouser or Digi-Key stated that the ISS was no longer available when I purchased the Dev board.
Seems like there are US laws against this.
