KCS Power PC Board, pics wanted

Does anyone have a KCS Power PC Board? The pictures on amiga.resource.cx show a large square 84-pin PLCC chip. The "rev 1" pic shows some of the text printed on that chip. But on the "rev 2" pic, any text on the chip is covered by a label. I'd like to find out what text is printed on the chip itself under that label.

(I've been looking at the supplied software programs to figure out how it works. At this point I think the large chip is some kind of CPLD or FPGA, and the software can send different configuration bitstreams to it.)

It is absolutely blank under the printed label. Just a plain black chip.

Thanks for that! Does it look like the top of the chip has been scratched or ground down to remove whatever printing was there originally?

My guess is, for the first hardware KCS got the chips custom-printed, and maybe for later batches they had the original printing removed instead. Assuming the chip is actually a standard part.
