Talk:Unisys 2200 Series system architecture

ones complement
This whole article doesn't mention that the 2200 series machines, like the 1100 series, use ones complement arithmetic. Seems to me that would be worth noting. Gah4 (talk) 21:57, 5 October 2015 (UTC)

36 bit word requirement
The claim that the DoD required a 36 bit word, rather than a 32 bit word, sounds very dubious to me. 32 bits were as good as unknown at the time, and how do you fit 6 bit characters into them? I'm flagging this with a "citation needed". Consider removing the claim. Groogle (talk) 05:00, 15 December 2015 (UTC)


 * I suspect that the comparison to 32 bits isn't true, but the requirement for (at least) 36 might be. Gah4 (talk) 14:29, 31 March 2019 (UTC)


 * I believe the correct explanation is given in the 36-bit computing article. It was not driven by DoD, but rather a general desire to process positive and negative 10-digit integers, and it was not unique to Univac. This is in agreement with my own recollection, having worked on OS2200 for 13 years in the 1980s. I propose to remove the DoD claim from the article and replace it with a reference to 36-bit computing. --MinnMike (talk) 04:37, 21 June 2021 (UTC)
