: "Saturn Ram Card" from Titan Technologies, Inc.
Saturn made RAM cards in several sizes. You should be able to
figure out how much memory the board will hold by looking at the
type of RAM chip on it now and figuring up what it would be if
fully populated.
Dynamic RAM goes random unless you refresh it every couple of
milliseconds. The cable on the 16K Language Card is there to
"steal" the dynamic RAM refresh signals from the motherboard; the
cable plugs into a RAM socket (the missing RAM chip is on the
language card). The Saturn boards had their own on-board refresh
circuitry and did not need to "steal" the signals from the
motherboard.
