Talk:ENIAC

When did operation end? '1956' in one paragraph but 'October 2, 1955' elsewhere

There's a one-year discrepancy on when ENIAC's operation ended. The "Operations" / Aberdeen-transfer paragraph says: "It was transferred to Aberdeen Proving Ground in Aberdeen, Maryland in 1947, where it was in continuous operation until 1955." A later paragraph specifies the retirement to the minute: "until 11:45 p.m. on October 2, 1955, when it was retired."

But the hardware-totals paragraph opens: "By the end of its operation in 1956, ENIAC contained 18,000 vacuum tubes, 7,200 crystal diodes, 6,000 relays..."

If ENIAC was retired at 23:45 on 2 October 1955, "the end of its operation" cannot have been "in 1956." The "1956" appears to be a typo for "1955" (or perhaps "by the end, in 1955"). Suggest fixing to match the precise October 2, 1955 retirement date already established elsewhere in the article. Rome (talk) 01:02, 5 May 2026 (UTC)
