For those who might be interested, there is a Google group called "SIA
People", for ex-employees and friends of SIA "Computer Services"
originally known as "Service in Informatics and Analysis". SIA
installed the first CDC 6600 in the United Kingdom and ran a
successful commercial batch and timesharing service. For more info on
SIA see Wikipedia entry:
