Figure 2-1 CP 1M -86 8080 Memory Model
The intermixed code and data regions are indistinguishable. The base page values,
described below, are identical to CP/M-80. This allows simple translation from
8080,8085, or Z80 code into the 8086 environment. The following ASM-86 example
shows how to code an 8080 Model transient program.
