Z80 / Kaypro emulator monorepo

• z80/ — M-cycle Z80 CPU library (libz80.a), freestanding
• emu/ — generic port-device framework, freestanding
• kaypro/ — Kaypro 4/84 CP/M machine + host backends
  • portable: kaypro/src/machine, kaypro/src/devices
  • desktop host: kaypro/src/host/posix (ESP32 host can plug in later via the same kaypro_host_ops_t)

make            # libz80 + kaypro_run
make test       # CPU instruction tests (56 asm vectors)
make kaypro     # kaypro executable only

Paths are relative to your current working directory. Fetch assets first, then run from the repo root:

bash tools/fetch_kaypro_assets.sh
./kaypro/kaypro_run \
  --rom kaypro/assets/rom/81-478a.rom \
  --disk-a kaypro/assets/images/dsdd/kaypro1.dsk

See kaypro/README.md for layout, host ops, and more run examples, and z80/README.md for CPU core details.
