This seldom found IBM antique is an original hand made computer core memory card for the 2821 printer.  These were used on the 1401 and 360 computers.  Note that these were the last of the large ferrite cores, hand made core memory cards of the 1950s to 1960s.  The card has 1600 bits in 16 quadrants each in 10 rows of ferrite cores.  Note too, that contacts were a high quality of gold contacts.  It is a very nice display of a 1960s IBM Computer Core Memory with very large cores (IBM started production of the 1401 in 1961).  This board also has supporting electronic plug connections.   The 1401 came standard with 4K of core memory.  It could be expanded to a whopping 16K.  As technology matured, the memory cores began to get smaller to pack more memory on a board.  Size 4.5”.  This rare treasure is from the 1401 printer buffer is a beautiful display of old computer technology and rarely found.
