Compulog Two Intercole Systems PAC 16

Anyone know more about this old 16 bit computer / controller? http://i.imgur.com/utUfMQe.jpg According to the current owner it is based on a 16 bit machine made by Computer Automation. It has core memory and is programmed in assembler and Fortran. It is from the late seventies. I found very little while searching the net. Intercole systems seems to still be in operation. PAC 16 could relate to Varisystems corp which I found in this document: ftp://bitsavers.informatik.uni-stuttgart.de/topic/minicomputer/ComputerDesign_Apr71.pdf In any case the Varisystems PAC 16 seems to be a rather simple 16 bit machine. But is this the same? And is Varisystems related with Computer Automation somehow? Any information is appreciated. Is it worth rescuing it? Any software to look for? The current owner has loads of 8 inch floppies.
