double-width card?


These two pictures compare an SMS (on the right) with an unknown double-width card. It is not a double-width SMS, is it? "Double-width cards are 5.375 inches wide by 4.5 inches tall" - the unknown one is 4.4 inches wide and 3.5 inches tall. Also, it has 18 connectors instead of 16 (but they are spaced the same). It has a date code of 1968. Does anyone have an idea of what it is? Bubba73 You talkin' to me? 01:54, 30 May 2022 (UTC)
