@greeting(Dear Professor Guzman:)

@begin(body)
	Many thanks for your @i[ A Heterarchical Multi-microprocessor
LISP Machine].  It comes in handy in connection with recommendations
for multi-processing in LISP for the S1 computer being developed
at Livermore.

	Do you have Harold McIntosh's address?  Herbert Stoyan at
Erlangen University has some questions for him in connection with
his history of LISP.

	Best Regards




John McCarthy
Profesor of Computer Science
