The file "prices.raw" in this directory lists the memory prices and other
information that I got by skimming through advertisements in Byte magazine. 
I looked at the January/July issues from 1988 to 1995 and picked SIMMS
that caught my eye (no attempt to be comprehensive or scientific about which 
adds I looked at)

The columns in prices.raw are as follows
Month	Year	Page	Size1	Size2	Access	Price	

Month--month of data
Year--year of data
Page--page in Byte where advertizement found
Size1--format of simm (e.g. 1x9 = 1M x 9 bits)
Size2--MB of capacity
Access--accesss time in ns
price--advertized price in $'s




ratio.go augments prices.raw with an extra column indicationg the
$/MB ratio for each line

year.plot creats a plot with year on the x axis and $/MB on the y axis
	year.gnuplot has the gnuplot commands
	tmp.plot has the (x,y) pairs
	year.ps has postscript
	year.mif has framemaker mif




The file prices.short.dat
is the summary -- what is the price per mb of the cheapest memory
at 80ns or better.
before 1/92, all prices are for 1MB/9 simms
from 1/92 on, all prices are 1/4 the price of a 4MB/9 simm
