dubious

... a storage capacity of 400,000 digits. Approximately 13,500 vacuum tubes ...21,400 relays ...very reliable for its time, making about one error for every eight hours

This was uncited. Sources I found do not agree and at best it is misleading. There is no way that many digits can be stored in that many tubes and relays. It seems to be counting the tapes as well, which is normally not done for computers. Will try to fix to match sources, but might take a while. W Nowicki (talk) 23:40, 24 April 2011 (UTC)

I located one of the rarly 1948 papers. The "eight hours" seems to be an example used, not any kind of measured nor predicted reliability. Also has other useful details that should be added. W Nowicki (talk) 19:50, 25 April 2011 (UTC)
