I haven't vanished.

I even did reply to your request. Seems you haven't got the reply, don't know why.

I have some chips for a replacement.

Has your card the Xilinx Xc17 variants or the Atmel ones ?

Well, then they have to be replaced. The Xilinx parts are one time programable the Atmel parts are Flash based and are reprogramable.

All the cards delivered by VT had two chips on them at this location because of the price.

These chips are simply chained and can be replaced by one larger(content) chip. So you can use a single xc17256 or an atmel counterpart instead of the two smaller ones.

You could also use two xc17128's.

As long as they provide enough memory you could use any combination as long as the first chip is completly programmed and the last one holds the rest that didn't fit in the first one.

usually it should be located into the 65's socket cause it needs to deliver the DONE signal to the FPGA.

If you get hold of the chips you still need to program them. That can't be done through software on the PIV. I guess you are aware of that.

I still have a small supply of programmed chips and I also have the equipment to program them.
