Somewhere I have a thing badged 'Princeton Ultra-X'. This is a pizza-box type slab that goes under a VGA montor and links to a keyboard and mouse and is, of course a standalone Xterminal. It uses an 80188 for I/O (including 10Mbps ethernet). The Xserver is in EPROMs and appears to run on the TMS34010 graphics processor. -tony
