Altera has their ByteBlaster JTAG programmer info available at:
http://www.altera.com/literature/lit-cables.jsp

Also see this site for a homebrew version of the Byteblaster cable:

Here is a schematic of a parallel port JTAG cable that works with the
Xilinx software:

For  Opensource JTAG programming software, (supports some Altera parts,
not sure if it supports the parts currently under consideration) see:
