101:(funded by the US federal government), they came back to Berkeley and collected enough information to begin manufacturing. Because SDS manufacturing was overloaded with the 9 series production and the startup of the Sigma Series production, it could not incorporate the 940 modifications into the standard production line. Instead, production of the 940s was turned over to the Systems Engineering Department, which manufactured systems customised to user requirements. To produce a 940, the Systems Engineering Department ordered a 930 from SDS manufacturing, installed the modifications developed by the Berkeley engineers, and shipped machine to the SDS customer as a 940.

When completed and in service, the first 940 ran reliably in spite of its array of tricky mechanical issues such as a huge disk drive driven by hydraulic arms. It served about forty or fifty users at a time and still managed to drive a graphics
