Abstract: A Bimemory Independent CPU (BICPU) microcomputer which is comprised of a known CPU chip provided with additional circuitry to enable CPU to interact in a multi BICPU microcomputer system. Each BICPU microcomputer in a system is supplied with an assigned standard memory mechanically and logically connected to it's BICPU's "A" bus circuits. The BICPU microcomputer is also provided with connectors enabling the CPU to be connected to system buses. Any number of BICPU microcomputers can be logically chained, linked and treed in a simple logical bimemory independent pattern infinitely in as many dimensions as is reasonably desired, using one standard set of dedicated, simple, single line conductors (system buses) to mechanically interconnect any "B" or "C" bus curcuits of two different BICPU microcomputers.

Abstract: An educational toy and method for demonstrating characteristics of a latticework of spacepoints including demonstrating (a) the commonality of latticework between tetrahedron configuration latticework and octahedron configuration latticework, (b) that octahedron latticework merges with tetrahedron latticework, (c) the 13-plane structure of the common latticework, (d) how simultaneous twinning in more than one of the 13 planes can form multitudes of combinations of domains of tetrahedrons and octahedrons, and (e) the altering of latticework by appropriately selecting the dimensions of structure members that define spacepoints in the latticework. Preferably, the structure members are similarly dimensioned and oriented ellipsoidal elements which are gravity stacked and optionally connectable and wherein the centerpoint of each ellipsoidal element represents a spacepoint in the latticework.

Abstract: An educational entertainment device includes at least one cube formed from (a) a regular tetrahedron and (b) four 1/8th sections of a regular octahedron wherein the faces of the tetrahedron and the faces of the octahedron are all congruent. The 1/8th sections are formed by slicing the octahedron through three orthogonal planes, each slicing plane passing through four vertices of the octahedron, each 1/8th section being defined by (a) one octahedron face and (b) three mutually orthogonal corner faces. By coupling the octahedron face of each of the four 1/8th sections to a corresponding one of the tetrahedron faces in edge-to-edge fashion, one cube is formed. Each side of the cube includes two corner faces, one from each of two 1/8th sections. By rotating a 1/8th section about an axis perpendicular to the plane interfacing the 1/8th section and the tetrahedron, the two corner faces forming a cube side can be altered. A plurality of n.sup.3, e.g. eight, cubes can form a block of cubes, in an n.times.n.times.
