The University of Illinois was involved in a line of performance orientated computers known as ILLIACs (Illinois Automatic Computer), with the Illiac IV the best known and likely most controversial computer of its time. We will use the shorthand IAC4 to denote the Illiac IV.

The Illiac IV was host 15 on the ARPAnet (1973 ARPAnet map showing Illiac IV), and most users were connecting from Host 16 to submit jobs to the Illiac IV. There were even users from the Imperial College of London connecting to Illiac IV via ARPAnet.
