Oh,  since I got no response from Pak21 on his comments page,  i'll re-enter my comment here: 

 Just put it on here as we've not heard from you in a while good Sir.  but in lines to what you said,  could we not put it up as "most commonly pronounced as "Zed Ecks Spectrum""  or "pronounced as "Zed Ecks Spectrum" in it's original British branding"?  That would be true and also be notable then?  

 I've noticed this subject has now crept up on a number of gaming articles now,  most notably the Sega 32X.   

 So if there's no objections, shall I re-add it?
