CP/M-386: CP/M for 386 protected mode, derived from CP/M-68K
This brings the classic CP/M operating system to 32-bit protected mode on x86 hardware, maintaining source compatibility with legacy CP/M applications while adding features like direct video access and high-resolution timing. The project currently lacks storage, network, and sound drivers, limiting practical deployment, but the BDOS implementation is complete enough to run existing CP/M software.

The BDOS is at full parity with CP/M-68K 1.3 and CP/M 2.2, with 71% coverage of CP/M-Plus and partial support for DOS-Plus and MP/M extensions.
The system runs in 32-bit protected mode with Ring-3 TPA and boots via MBR floppy or GRUB Multiboot, but currently has no storage, network, or sound drivers.
Building requires cpmtools version 2.23 or later, NASM, and GCC or Clang, with known issues on FreeBSD's cpmtools packages that require rebuilding without libdsk.
