	It is true.  The chips are 256Kx4 configuration 120ns or faster.
You can populate the board for 0K, (the cheapest route), 512K, 1M or 2M.
I just added 2M for $135.  Works like a champ.  The 2091 RamTest program
is rather "neat."  You get a picture of the board while testing is performed.
Overall, I am really impressed with the 2901 software.  IMHO, HDToolBox is
much better than Supra's stuff.  I would like a way to specify interleave,
and buffers in fast RAM.  300K reads/writes are much better than I had, but
I was wondering if that is the best I can get on my 2000.  2500 users see
~700K transfer rates.

The above are my opinions, which NCR doesn't really care about anyway!
