Project Description

__edsac__ (Electronic Delay Storage Automatic Computer)

edsac [ __-h__ ] [ __-v__ ] [ __-f__ __FILE__ ] [ __-r__ __REPRESENTATION__ ]

__EDSAC__ (Electronic Delay Storage Automatic Computer) is a simulator capable of executing __EDSAC__ I computer's stored-programs.

__-f__, __--file__ = _FILE_
Specifies the input file.

__-r__, __--representation__ = _REPRESENTATION_

+ `` traditional easy_install or pip
+ `setup.cfg` for distutils2 installation
+ `scripts/edsac` executable binary
+ `edsac/` a separate library packaged version
+ `edsac/` edsac grammar
+ `edsac/` edsac lexer

There are some programs included under stored-programs directory. Different ways of simulating stored programs are shown below.

MrmacHD:~$ edsac -f stored-programs/Hello.txt
MrmacHD:~$ python3 edsac -f stored-programs/TypeWriter.txt
