While I can appreciate the spirit of what you are trying to do... I don't see it as being too practical. With parts of interesting density, the cost of coming up with a board to put them on is going to be greater than the cost of buying a few of them from the likes of digikey... and then, for a one off, the true economics are going to suggest turning an eval board into your device.

Recycling programmable logic doesn't make a lot of sense to me, unless perhaps you find a way to use it on the board it's already on, perhaps to improve the original device... that, could indeed be fun.

Your list should include 'model number' to it feasable to find the product aswell.

Ie: Vendor: Creative Model: SoundBlaster X-Fi Elite Pro

Product introduction date also makes it easier.

Thoe I have to agree that the economics is doubtfull.

The EPM7064 isn't ISP capable. You need a special programmer. I was just given a handful and discovered this myself. There are newer EPM7000 series parts that DO have JTAG and ISP.

Indeed -- that's what I meant by 'Vendor Prog.' in the list; the 'S' versions are ISP though and from that vintage.

Thanks for the reply :)

I agree that RE of a peripheral board with programmable logic to permit reuse or improvement is always interesting and useful. For many folks it is also true that scrounging for parts of even modest density is cheaper than small quantity purchases even considering time involved in depopulating and remounting on breadboard fixtures.

I am exploring the reuse of ceramic PGA (old CPUs) as a carrier for large pin count flat packs; the ZIF sockets are in abundance from old mainboards and using a cutoff wheel on a radial arm, one may open the PGA packages to expose the pins for soldering.

Agreed, whenever known that data would be helpful.
