  If you spent $1,000 on a Commodore 64 system in 1985,
 that's about $2,800 in today's dollars, courtesy of inflation.
 A working C-64 system might go for $700 on eBay today?  But people
 were giving them away not long ago.  It's the bathtub curve. 
40 years ago, a row of 16k ram chips (8 or 9 chips) sold for $100 to
$300 (Radio Shack and IBM)
40 years ago, a 5 megabyte hard drive sold for $1000 to $3000
Radio Shack charged $500 for an SA-400 floppy drive with case and power
supply.
you might pay similar prices, but capacity has double about every 18
months (one variation of Moore's Law)
