The island of Guernsey contains two sculpted menhirs of great archaeological interest, while the dolmen known as "L'Autel du Dehus" contains a dolmen deity known as "Le Gardien du Tombeau".

SIMMON virtual machine for testing of a single guest program running there. CP-40 supported many virtual machines for time-sharing production work. CP-40 evolved by many stages into the present VM/CMS operating system. SIMMON was a useful test vehicle for many years. SIMMON was designed to dynamically include independently developed programs (test tools) for testing the target guest program. The SIMMON kernel maintained control over the hardware (and the guest) and coordinated invocation of the test tools. Two modes of operation were provided: In this mode, each instruction in the guest program was simulated without ever passing control directly to the guest.
