NewBrain in Angola

The Central Planning of Angolan Ministry of Commerce in Angola between the years 1981 to 1984 used a NewBrain Computer.It was strange that a small NewBrain with two cheap cassettes and one MX100 EPSON printer managed to recalculate all of the central plans of the Ministry of Commerce in less than 4 hours, while one IBM 370 mainframe computer costing millions could not perform the same operation in  less than 2 months, as things like "re-programming", "punching cards", "lots of energy", "High class analysts and engineers" were necessary.
