TRIUMF’s Central Control System has a large investment in CAMAC. To protect this investment but allow the current trend of PCI-bus based computers to be supported, TRIUMF has configured a PCI to CAMAC system. In this setup, TRIUMF has connected PCI based computers into the CAMAC equipment of their Central Control System. DEC Alpha computers running OpenVMS have been interfaced via the PCI bus to the existing CAMAC executive crates. The PCI bus is connected to a Q-bus expansion chassis using a commercial interface and then from the Q-bus chassis to CAMAC via a TRIUMF interface. This paper describes the hardware and software interfaces, and performance issues.
