This article contains examination of hardware-based “architectural clones” of mainframes external devices, namely adapter of interface with channel. It is noted, that the software-hardware interface of external devices emulator is based on personal hardware. Hardware part of emulator is an adapter of interface with mainframe channel, engineered on the base of PCI-Express technology. The methods of interface adapters development were produced and their brief ratings were given.
