    ENTREX INC. / NIXDORF COMPUTER (Burlington Massachusetts)
    8K core memory board & stack
    Pulled from a retired Entrex / Nixdorf Model 480 Mini Computer System
    15" X 15" 16 bit Data General Nova Base Board from the mid 1970's
    Date codes on most of the IC's are 1974.
    The sticker on the back indicates it was inspected by quality assurance in 1975.
    Memory Board is 15" X 15"
    Chances are the stack was made by EMM but didn't want to remove the cover.
    It probably still works but there is no way to test.
    32 Data Terminals were connected to the 480 system running with 4 of these boards.
    The hardware & software was incredible to maintain data transfer
    of 32 keypunch operators typing all at once on just 32K of memory.
    A very rare find & real nice piece of vintage & early computer history.
    Being sold as is with no returns due to the age.
