Re: Strange but UNtrue
Also "the Met's 30-year-old command-and-control system"
In 1989, I worked with the Unisys guys (no gals IIRC) converting the old Sperry 1100-based system onto flash new Unisys 2200 hardware. The system was certainly already more than four years old then, so I'd put the system age at more likely 35 to 40 years than a sprightly and youthful 30.
I'd expect that the software was based on systems designed and written by PRC, a US-based Sperry partner who specialised in "Computer Aided Despatch" applications on Sperry hardware. I guess it could be used for taxis, but the package and the hardware it needed cost several millions of dollars (US) in the 1980s, so I doubt very much it was affordable by any taxi company.
