[Central-Electronics] re crt for CE100V & CE200V

[Colin Lamb]

The P5 phosphor is generally considered as "medium short persistence used for photography".  The writing speed is not important in the application for which it is used.  It is a bluish rather than yellow green.  It may be dimmer - but it is possible that could be compensated for by increasing the intensity.  

My favorite phosphor is the P7 - but it is not very common.  It had a very long persistence and was great to show the full waveform before it decayed.  

But, heck, I like the odd ball stuff anyway, so I am not a good source of information.
