The architecture for the Series 68 and 70 computers is significantly different
than the other HP 3000 series. as shown in Figure 1-3. The CPU and memory fit
into the Central System Bus (CSB), and one or more IMBs connect to the
csa
via
Common Bus Interfaces (CBls) and 1MB Interfaces (lMBls). I/O DMA
operations do not go directly to memory, but are handled by the IMBI.
