Talk:JOHNNIAC

From Wikipedia, the free encyclopedia

Various sources refer to the original tube-based adder being an analog unit. This is odd, does anyone know how this would work? D-to-A and back? Maury 22:08, 27 March 2007 (UTC)

One source suggests the "breakage" due to storing data in the unused bits occurred much later, in 1962 (IIRC) There's also some confusion as to which bits were used, the two upper address bits, and/or bits in the instruction portion itself. Maury 21:23, 28 March 2007 (UTC)

The second N in JOHNNIAC stands for Numerical. Evidence (from vhttp://www.rand.org/pubs/research_memoranda/2005/RM5654.pdf page 1 (the eigth page) footnote): von Neumann didn't want it named after him but the response was "there are plenty of other Johns in the world". No mention is made of John Ns.

I actually imagine that the NIAC part matches that of ENIAC: Numerical Integrator And Calculator. I don't immediately see support for this. —Preceding unsigned comment added by DHR (talk • contribs) 22:32, 6 February 2008 (UTC)
