I admit I don't know what I'm talking about, but I suspect there is
software available that would allow you to use the 486 to monitor the
Pentium, if you hooked them up in parallel - maybe a simple communications
program would log everything.  Then you could have the "fun" of figuring
out what is actually going on.
