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! Paul
