BEX
I also remember the Watchman console. On one idle and horribly foggy afternoon I used the drawing and text facility to copy the built in test grid onto the screen. I then complained to Tels that I couldn't switch off the test grid! Took them about an hour to tumble it. I also remember the facility to show the filtered out wx returns as a "ghost" image. You could see the targets clearly, you could see the wx clearly and it didn't take ten minutes to update.
