Please forgive me, this is a very newbie questions probably....We had to replace a Data-Ray DR5614 CRT - got a used one and it is okay. We are obviously getting old because we need to make the text size on the display bigger! Can anyone tell me how to do this - obviously we don't have a manual or anything - CRT was a direct swap. It is running on a Toshiba machine retrofitted to a Mitsubishi controller. :drowning:
