Natami did have a phased approach to development. The first prototype "Natami 30" was an add on for a modified C-One, their was a Zorro graphics card for the 3D core, Natami LX prototype, Natami MX prototype and two 68060 expansion boards.
Not enhancing the graphics to some degree would have been crazy when the idea of Natami was to provide a practical system for use as a main computer in the modern world (not outperforming the latest PCs just capable of doing the basics). There were some crazy performance claims being made by an individual member of the team for the soft core 68K processor and graphics, apparently without consultation with hardware designer Thomas Hirsch and this I believe led to the break-up of the team. With nothing more heard of the hardware in the intervening years I can only assume Thomas lost interest in the project. It's a shame as the hardware looked very promising and a lot of money and effort must have gone into the project. The "project" by Harold Neufeldt also made some very dubious claims and without anything like the tangible evidence of it being realistic that the Natami hardware had.
