\F1\CA Proposal for an Interactive Computing Laboratory
\J
The computing paradigm of the 1980's will be highly interactive, personal 
computers that maintain intercommunication through networks.
This style of computing offers application and technical challenges
as different from time-sharing as time-sharing was from batch mode.
To prepare the University for these challenges we propose a modest
local network whose capabilities can be modularly 
enhanced either by adding new nodes or by 
upgrading existing nodes with more powerful processors.
\.
\CUndergraduate Applications
\J
E3 The system will support UCSD Pascal, as well as a full array of more traditional
language systems and program preparation aids.

E10 The system has the potential (see hardware section) to support graphics
and computerized mechanical drawing.

EECS15 UCSD Pascal, TLC LISP, and Rosetta Smalltalk will all run on this 
system. Each language system offers its unique and valuable perspective on
data structuring.

EECS101 Same considerations as EECS15, but emphasis on in-depth performance in specific languages.

EECS xyz (Operating Systems) System  will be useful for  development, and
indispensible for experimentation with implementations of operating systems.

Special topics  courses: This system is an integral part
of the Spring 1981 course, The Art of Computer Science. 
Further possible topics include: network architectures,
distributed computation, interactive programming systems, 
computer graphics, intelligent computer-aided learning, 

Freshman induction course: The system will give students an
accurate view of interactive computing, including an 
introduction to the benefits of interactive technical writing.
\.

\CGraduate  Impact

\JThe system is valuable in at least 301, both parts of 310, Functional programming,
Artificial Intelligence, and Operating systems.
