No, it would be a million.....   per year....  (but I'm not quite sure it was 
that high but it was mighty expensive.)

But one day one of the IBM PC  (Aug 1981), it *was* $1,000 for a meg of PC 
ram.

I remember paying $640  for an add-on memory board of 640K.  (or was it 64K?  
which would make it $10,000 per megabyte)
