This is a copy of the rare and seldom found 1953 IBM 701 Scientific Calculator Computer Pluggable Unit with 8 vacuum tubes called “The Modern Abacus” (note – this is a very nice copy of original ad on glossy photograph paper).  The 1953 IBM 701 computer was the most powerful machine of the period and was used in business and especially USA government defense for calculations.  This was the first of IBM’s 700 series of scientific computers.  The Advertisement calls this the “Modern Abacus”.  A portion of advertisement reads: “Resembling a Chinese abacus, this electronic assembly operates at a speed of one million pulses a second.  It is one of 274 similar electronic units that perform the computing and control functions for the 701 computer…….”.  Size of Advertisement Copy is 8” x 10” and without our copyright.  In our eight, 8, years at Ebay we’ve only found one, 1, of these original advertisements and we paid over $ 200.00 for it.  This is truly a beautiful and very rare piece of computing history from 50+ years ago.
