[SIGCIS-Members] Older computers (1940-1950)

Hi all,

I am not sure why this discussion thread seems to be going out of its way to degrade the importance of the ABC machine.  The computer was conceived in the late 1930s and became operational in 1942.  Granted, it was not a general purpose machine, as some of the other machines on the list.  However, it is generally acknowledged to be the first electronic special purpose computer.  Furthermore, in the protracted court case with the ENIAC on the patent of the computer, the ABC prevailed.  It may be worthwhile to visit the URL http://jva.cs.iastate.edu/operation.php , and see the birthplace of the ABC.

Thanks for your consideration.

If we include the ABC, we may as well add Couffignal's computer, an

electronic, parallel calculator programmed from an external disk.

I agree about ABC being of a different, lesser class than the others on the list. Hadn't heard of Couffignal, very interesting! _____________________________________________ This email is relayed from members at sigcis.org, the email discussion list of SHOT SIGCIS.
