This might not be the first 709 system built, but the CPU does have serial number 1. It was said that data channel traps were developed on this machine. This is one of the three 709 systems that were modified to run IBSYS. The system is complete except for the line printer but has been cannibalized somewhat for parts. Also much of the trim, especially for the memory, is missing.

Serial Number: 11001
