A continuous container-supplying apparatus in which a plurality of container holding assemblies, each comprising right-side and left-side holding members are provided on conveyor belts that run as an integral unit along an annular track that has a pair of parallel sections. Standard electrical fuse hardware chains provide a soft test feature wherein the effect of memory slow-down can be tested prior to actually programming the fuses. The apparatus also includes a primary array to store a mapping from logical registers to physical registers, the primary array storing a speculative state of the processor.
