Diebold claims that it can't turn over the source code for their operating system.
How convenient, since they modify it, and we don't/can't know what that modification does to the counting of the votes, without examining it closely.
Non techies don't understand - the operating system DOES affect how votes are counted.
Furthermore, Diebold modifies the Windows operating system,
Jeffrey Dean, a convicted felon is known to have modified the Windows CE operating system used by Diebold.
Jeffrey Dean used his talents with computers to rob a business.
Jeffrey Dean was released from prison in August, 1995 and Elder was released in November 1996...
Jeffrey Dean, when released from prison, had $87 in his inmate account. He was ordered to pay $385,227 in restitution for his embezzlements. For most of us, this would be a crushing financial blow, and we would find it difficult to bankroll a business, yet somehow Dean (and his wife, Deborah M. Dean) managed to become the owners of Spectrum Printing & Mailing. In 2000, Dean’s printing and mailing firm was purchased for $1.6 million by Global Election Systems.

Furthermore, it is emerging that the version of Windows CE used by Diebold is both heavily customized and full of dynamically loaded libraries. As a result, there are strong grounds for the conclusion that the operating system is not unmodified commercial off the shelf software (COTS), and that with this extensive use of dynamic linkage, we cannot even tell if the system being run on a particular voting machine resembles the system that was disclosed in the configuration documents submitted with this system when it went through the FEC/NASED approval process.

"Williams does acknowledge, however, that a month and a half before the November election, he worked with Diebold to apply a patch to the Windows CE operating system. The voting machines run on version 3.0 of Windows CE, he aid, and they patched it to correct problems they were having with the ystem"
