See here for an overview of the chip and the photographs we have of the die. As of late March 2011 we have vectorised polygons and a transistor level netlist, which we hope to publish soon.

Here are JPEG images of the recaptured polygons - these may be easier to explore than the svg format:

Medium size Full size (14Mbyte)

We have a JavaScript simulator available here (graphical mode) (non-graphical mode)

Here's the block diagram from the 1976 topology patent (See also this later patent.): M6800-arch.png
