According to the text, the system used Bunker-Ramo Teleregister Model 203 display stations with a "full alphanumeric keyboard, a bank of function keys, and a CRT screen on which twelve lines of 32 characters each may be presented". Was the photo of a 203? Were the characters on these terminals stroke generated, or raster? It seems that a lot of early character displays were either stroke generated, or used charactron(sp?) tubes (electron beam first directed through a mask with character stencils, then deflected to the correct position on the screen), with raster coming later. I knew Bunker Ramo made terminals, but had no idea how early some of them were made. Rick Bensene
