I have a total of four 19-inch CRT monitors in the workshop, all acquired from FreeCycle! Then there's the green screen monitor in the Stag PPZ EPROM programmer, a 6-inch mono TV that I got from a car boot sale, an HP logic analyser (1630G) with a CRT, and a number of CRT scopes. Plus, whatever CRT I have currently got wired up to the Compukit UK101. Unfortunately my Philips CM8833 colour monitor failed at the Maker Faire in Newcastle -- the line output transformer has developed a short that shuts down the switch-mode power supply.
