Yes! I just repacked my lidless 4116 chips. I only ever got as far as
cementing slide-mount covers on one and sticking it in an Apple II at the
top of RAM and demonstrating the effect by clearing video RAM then lifting
the lid. Many bits sparkled in when light shone on the chip.
Now that I have a digital camera, I'll have to take pictures (as soon as I
buy/find/make a Mac crossover cable to connect a QuickTake 150 to my Mac).
