Okay, I stand corrected!  Sorry for being bull-headed!  I had never seen
a RAM with quartz window, and I still can't see ripping the top off of
an ordinary RAM--any way you do it is going to contaminate or destroy
some of the chip.

As for the circuit cellar project:  Not suprising I missed that.  I
am an Amiga user, and Amiga users typically avoid that Byte magazine
like the plague (as they avoid the Amiga like the plague!).

Thanks for the daily humbling!
