This memo is the second in a series responding to the request that I work with ED to
develop task plans for the LSI Digital Processor Program to which monies, headcount,
and Altos have been allocated in 1978 via a transfer agreement for son
responsibility spending in ED. The first memo in the series, reference A, is attached
for your convenience; it has thus far generated a response from ED in Howard
Kakita's memo of 17 May, reference B, in which it is agreed that ED/EDC's LSI
Digital Processor Program (1) will begin in June, (2) will produce an LSI DO
Requirements Specification in September, and (3) will result in detailed task plans for
SDD review in December.
Following the interview with Chuck Thacker which led to reference A, I met with
Butler Lampson to get his ideas. Butler was in general agreement with the contents of
my previous LSI memo, reference A. In the following, based on my conversation
with Butler, I attempt to take the next step in resolving a few major strategy
questions. White Chuck and I and now Butler see eye to eye on many points, I take
the liberty here to state things only as J see them, not attempting consensus. Perhaps
some controversy will result this time. You
