[sdiy] 566

[Paul Higgins]

NTE (yeah, I know we all usually hate NTE) makes a supposed cross for 
the 566.  I saw it at Mouser.  No idea whether it will really behave 
like a real 566, though.  I know that some of the old circuits that 
used the 566 had to be performance-tweaked if the original chip had to 
be replaced.
