I see he also has an Apple II that he wants $2000 for --- it's listed as "NON
WORKING ELECTRICAL COMPONENTS FROM EXTREME AGE", and from date codes and
copyright markings it appears to be far from original. In fact, the
motherboard seems to be a Rev 7 RFI motherboard, and the processor is (I
think) from 1985. If that one is worth $2000, my Apple IIs must be worth at
least $6000 each :-)

I brought the RFI thing up with him.  No response.  There is a legit Rev 1 there too asking $3500.  I don't find Apple IIs below Rev 0 that interesting anymore, personally.  I think even the legit guy would struggle to get much above $1500.
