Honeywell has signed some kind of licensing agreement so that they can use the chip set. Some general info follows, but be forewarned that my information is skimpy and not necessarily up to date. Perhaps some of NCR's people from the West Coast plants will comment and correct me where I'm wrong. The NCR/32 CPU and MMU are supposed to be available in 8Mz versions. The CPU is known as the "CPC" (Central Processing Chip????) and the MMU is called the Address Translation Chip (ATC). The other support chips are a serial I/O controller (SIC), an math chip (EAC) - whatever that means - (its an FPU of some kind), and a VAC - Virtual Assist Chip, that offloads the CPC in a virtual address environment. The CPC contains 16 general 32-bit registers and is microprogrammed externally. More info should be available from your local sales office. But you'll probably have to push it. Another development of possible interest is the GAPP chip. It's a an array of 72 processors on a single chip. GAPP is reportedly 10x faster than the system it replaces, with a 8 to 1 size reduction. The chip was designed for Martin Marietta and will be used by them in military applications of image processing. NCR retains marketing rights for commercial and industrial applications.
