Yes, I always loved our Office Plotter when I was working for HMCE. Our Tariff-related project was being attacked using SSADM* and we needed very large DFDs (Data Flow Diagrams), ELHs (Entity Life History) and a few other TLAs. (Three Letter Acronyms). They were in the days when the 386 was the state of the art office computer. The plotter would be chuntering along to itself for hours.
