Wanted: X/PEX terminals

The recent discussion of VXT2000 reminded me of X/PEX terminals. I'm looking for X Window System terminals, particularly early NCD models before they switched to using PC keyboards. I have several NCD 19s, see right hand side of this photo: <http://manx.classiccmp.org/collections/cgm/sprawl4/dsc_0608.jpg> However, I don't have any of the color X terminals from NCD for that period. Also, I have *no* PEX terminals and this would be a very welcome addition to the collection of the computer graphics history museum. I have a number of small box type X terminals from NCD, Tektronix and IIRC even an HP branded one. They are from late in the X terminal marketplace where they all had become fairly identical: small rectangular boxes to which you attached a PS/2 keyboard and mouse and a VGA monitor. I can post a list of the exact inventory in the museum's collection if that will help avoid duplicates. -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
