All the programming cables for Lattice,
Xilinx, Atmel and Altera (and presumably Actel) are similar.
Just buffered parallel port lines with AC couple caps and
series termination. Though the DB-25 pin out varies. I ordered
PCBs to also build programming adapters for the JR-IDE boards,
but the parts kit cost totaled $10 w/o PCB only to find fully
assembled ByteBlaster II cables on eBay from Hong Kong for $16
shipped to the states. doh.
