Dear Gordon:


Here is a copy of my letter to John Leng.


I looked into the questions you raised concerning the  feasibility of

debugging a  processor of  the complexity of  Super Foonly  and found

that Poole and company had already produced a write-up on the subject

(enclosed).  It  was prepared  for the  design review  and was  to be

presented the second day, but somehow we never got around to it.


I find the enclosure fairly believable.  How about you?


Sincerely,



Lester D. Earnest
Executive Officer
