Tim, I have experience with the Lattice's ISP 22V10, 1016, and 2032 and
I have'nt had the problems you mentioned though you have obviously tested
this. I did have a problem with a 2032 that kept insisting it was protected
under pDS and Synario. Exporting the file and using ispDownload worked
fine. It looks like my software needs to be updated and I'm fortunate that
Lattice is local and the rep is giving me the "Jungle Pack" with updated
software.

   How does this relate to the PIC? ;-) Well, I use their 1016 to emulate
generic Motorola and Intel uP signals off of a PC parallel port. It allows
me to test a variety of peripheral chips and PIC interfaces. With a 1016,
I get an 18 Bit address bus, 8 Bit data bus, and related control signals.
It's also good for programming memory chips...
