those were _REAL_ ICE (In Circuit Emulators), I haven't seen an ICE 
since the days of hte i286.


SoftICE was a software debugger that had some ICE like functionality, I 
remember it as a Windows kernel debugger.   I believe its now history, 
the company that created it was swallowed by someone else who later 
decided they didn't know what to do with it so they buried it.
