I have some 256kX4 bit, 100 ns, ZIP package DRAMS I want to install
in my A2620 card.  It says in the manual that the square edge is 
pin 1's edge, but a mark on the back of the ZIP enclosure indicates
that pin 1 is on the rounded edge.  There are 2 round dots on the
front of the ZIP package, one on the upper right hand side (square
side) one on the lower left hand side (rounded side).  
Where is Pin 1 of a ZIP package DRAM?  I think it must be
towards the rounded edge, by the lower dot on the front of the
package (by lower I mean closer to the metal pins).
