They all seemed to be remarkably similar inside, and by the time I was about 14 I got to be reasonably good at fixing them. My first "video monitor" was a cast-off 405-line 14" 'portable'. I stripped out the tuner (it was a turret tuner and almost every segment was broken) and some of the RF valves. It had a series heater chain so I added a few high-wattage resistors to make up for that, and tweaked the circuit a bit to handle the video from my first Exidy Sorcerer. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York
