Well, how about running a co-processor instruction and seeing if anything happens? If on an 8088 a coprocessor instruction is executed and there isn't anything there listening to do anything with it, *nothing* happens (suprise?) Although this will require a little assembly language (horrors) it is pretty foolproof..... -- I've got one, two, three, four, five senses working overtime, trying to take this all in!
