We used to use those quite a bit, at least EP320's and EP900's. I know that 
some generic programmers can program them, so I dont think the programming 
info was proprietary, not sure about the 'fuse maps'. The Altera software 
system used a funny source language (.ADF files if those brain cells are still 
working right).

These days I'd just use a XC95NNXL and have 5V tolerance and in circuit JTAG 
programmability, (and not have to wait for the UV ERASE every time I make a 
mistake)
