      So I took a quick look at some pictures of my Sol before I removed the Dutronics Z80... It looks like the wire that hangs off went to an input JK flip flop to get a signal from the S100 bus pin either the PRDY or XRDY, can't tell which pin on the flip flop.

      I hope that helps....

      Cheers,
      Corey
