IBM 5155 Portable PC CRT Sacrilege

I always thought the white looked cool but I am partial to the amber and green. The amber color reminds me of the monitor on my first computer (a 5160 w/ a Hercules compatible card) and there is something soothing about the slow fade of the green phosphor. I say leave it be unless it really bothers you, and if it does then you can always uses a 5153 w/ the 9 pin connector or another monitor with the composite connector. -Ali -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Paul Koning Sent: Thursday, August 28, 2014 2:13 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: IBM 5155 Portable PC CRT Sacrilege On Aug 28, 2014, at 3:34 PM, Sam O'nella <barythrin at gmail.com> wrote: DEC terminals were initially white (VT05 through VT100). At some point in the VT220 era, green and amber appeared as alternate colors. Somewhat after that, I think the original black & white TV set style white changed to "paper white". It would be interesting to find out the sales proportions of the three colors. I remember them all; I never saw more than a handful of either green or amber. Early on, green was associated with long persistence displays - the GT40, the CDC dd60 console, etc. I know early IBM terminals (like the ones for TSO -- 2550?) were green but I'm not sure why. Amber showed up much later and as far as I could tell was just a fad that appeared briefly and went nowhere. The eyestrain argument has been made for any number of colors, even plasma panel orange. I don't know that it was ever more than marketing fictions. The only difference I know of is that some people like one color and some prefer another. paul
