From the collection Dr. David P. Chandler on the site http://papaintellivision.com/
The documents herein regard the Mattel Electronics Intellivision project ranging from its inception in 1977 until the end of Chandler's involvement with the company in 1983.
This document, undated (though probably from 1978 as the system is still unnamed), shows a more formal mapping out of the memory in the Mattel Video Game hardware. This displays both RAM and ROM. The Executive program developed by APh is present along with allusions to future addons in the form of “tape” and “cable” sectors.
