Emulator
For testing software on a modern machine, the most convenient option is the M2000 emulator. M2000 emulates the Philips P2000T and is useful both for running existing software and for checking newly built cartridge or tape images before trying them on real hardware.
The emulator is maintained in the p2000t/M2000 GitHub repository, where you can find the source code, build instructions, and release information.
