I've started something of a collection of FPGA dev boards and picked this one up recently.
I am looking for some files that seem to have disappeared from the internet as this person also notes https://support.xilinx.com/s/question/0D52E00006iHjJ4SAK/need-ml50x-cf-factory-files?language=en_US
With Internet Archive we can find some record of the content http://web.archive.org/web/20130118043528/http://www.xilinx.com/univ/xupv5-lx110t-refdes.htm but there are no download links. I would be particularly interested in the base demo CF image and some of the reference designs on this page as well as the CPLD source.
