[comp.sys.mac] Are these MacIIxi SIMMs for real?

TONNIES@cc.utah.edu (B. Tonnies) (02/23/90)

A blurb in the rumors column of the most recent Info
World indicated that the only SIMMs that could be used
in the soon-to-be-released MacIIxi would be of the type
used in the LaserWriter NTX.  It went on to state that
these SIMMs run upwards of $500/Meg and would only be
available from Apple.  

Does anybody know if this is to be the case?  If so, 
would anybody care to describe the difference between 
currently available $79/Meg SIMMs and these NTX SIMMs?
Is their price justified?  Is there a valid technical 
reason for Apple to be using them in the MacIIxi?  (I
hope it is something other than the fact that Apple is 
sole distributor for these SIMMs at >$500 a pop.)

Thanks.
