1975 Dollars (was RE: State of the Hobby)

I think you have that backwards, sir. The present value of the 1975 dollar
is $2.95, not the other way around. This is clearly just a misstatement, as
you've interpreted it correctly in the subsequent statements of present
value.

This implies that when eBay facilitates an auction of an old Altair for
$3000 it's $2500 lower than what a new one cost. That's not so bad,
considering that the original was probably not built up and not functional.
I note that the last one I saw for sale there hadn't even gotten a bid from
$3k to start after 4 or 5 days. It would appear the guys who buy these
aren't all totally stupid out there.
