I've been looking for the CRT phosphor specs for type P40 phosphor, without
much luck. Supposedly, P40 is similar to P4 but with a slightly different
hue and different decay characteristics.  The info is probably in the
EIA CRT specs doc., but unfortunately, I don't have one (the doc costs
over $40).  I'd also like to know what phosphor is used on the Xerox Alto.
When I used one, I noticed that the screen seemed "whiter" than P4.
