I believe that I saw a posting that stated that apple shipped SE's and Pluses
with the 120ns chips after jan 1987.  I have a plus that I purchased in Jan
of '88, and it has 150ns chips.  Also, I have done upgrades on several SE's
that are relatively new... and I have seen both 120 and 150 ns chips.  I
have even seen an SE with 120 and 150 in the same bank!!! (I understand taht
this is not supposed to be a functional configuration).

Anyhow, the whole point here is... if the chips have a number ending in 12,
they are 120ns, if the number ends in 15, they are 150ns... and if then end
in 10, they are 100ns.  Only 120 or faster work in the II.  

Now that that is all said and done... I have 4x256K SIMMS, 120ns, for sale...
If anyone is intersted, I will entertain offers.....  (I also have a whole
slew of 150ns simms... if anyone really wants them.)
