This emulator supports ADM-3a used also on the very popular Kaypro computers.Back in a day, most computers were desktop machines with the main goal for the hardware, to offer absolute best performance and there was no real need for technologies such as SpeedStep, Turbo Boost etc. Applications needed to be aware and usually could be configured for several leading options, like ADM-3a, VT-52, Hazeltine 1500 and Osborne. CP/M does not define how the terminal should work. The CPP binary from CP/M 2.2 can be used optionally. See cpmish for other open source alternatives to the CP/M binaries. Traps the calls and executes code on the host. In theory, it shouldn't be necessary, but some programs use it directly, bypassing BDOS. To emulate this environment using the host filesystem, we have to provide a replacement BDOS translating as we don't want to relay on the physical disk sectors abstraction of the BIOS. Provides the high level entrypoints to be used by application developpers. Provided by Digital Research and common to all systems. The BDOS: Basic Disk Operating System.The hardware vendors provided the BIOS for their device based on source code available on the CP/M distribution. CP/M defines a very small interface: 16 entrypoints to manage I/O and access to disk sectors. Mmm, not in CP/M.ĬP/M was designed to be portable to a variety of devices using Intel 8080, Intel 8085 or Zilog Z80 processors thanks to a tiered architecture.
