I hate to be a MOTO (Master Of The Obvious) but ry putting back the 5Mhz CPU
What was wrong with it in the first place? You can't get the thing to run
faster just by changing the CPU. You are _obviously_ not a EE (BTW I am ).
If the old one broke buy an 5Mhz replacement. 
	You may have also destroyed it with ESD (Electro-Static Discharge)
while replacing it. You have to very careful with those puppies one slight
touch and...   ZAP!!!!!  they're dead.
	My suggestion is that if you have the old one, put it back. If you 
don't, get another 8Mhz(*sigh* if you must) and try that one. If the new
8Mhz works, then you zapped yours if it still doesn't work, buy a 5Mhz.
	The system was designed to work with a 5Mhz. You, the super stud
comp. sci. person that you are, should know how important timing signals
are when components work together.

What were you doing F***ing up someone else's robot for???
You should've gotten a tech. to work on it!!!! TSK, TSK!!

Good Luck!!
