Well, an Apple-1 could be faked for a reasonably moderate amount of effort
for a rather large return ($5K+). I know there are some parts no logner
available, like (was it the) shift register? But still, enough searching
in electronics surplus shops would eventually turn those parts up. A
couple or three or four replicas could be produced and someone could end
up with between $20K and $40K.

I really should read the entire message before I add my comment :)

Consider that a Mark-8 is probably very simple to re-produce (save for the
8008 chip) but could sell for upwards of $1K each on the current ebay
market frenzy. The original PCB layouts are still available too. Same
goes for a Scelbi.
