Has anyone ever thought to ask if the software could be read from the units on display? 128.194.22.23 18:01, 19 February 2007 (UTC)

I know someone has tried to get hold of the software without any luck so far. I don't know whether they've tried to get access to the displayed Saturn IUs, or whether reading the core memories would even be feasible without specialised hardware. Mark Grant 00:32, 20 February 2007 (UTC)

"with a 2.048 MHz clock cycle, add operations taking 82 microseconds" So "add operations" took 168 clock cycles? Is the LVDC is a kind of serial computer? --68.0.124.33 (talk) 06:09, 4 March 2008 (UTC)

I believe so, yes: the documentation says "the Add/Subtract circuit serially adds or subtracts the contents of the accumulator, the contents of the addressed memory location and any carry that develops from the previous bit summation." Would be worth adding some more info about how the internals worked but it's not particularly clear :). Mark Grant (talk) 02:04, 4 June 2009 (UTC)

I have some LVDC Core Memory Blocks and Page Card Assemblies within my private collection that are photo documented with a description of the LVDC on my personal website. The direct URL is http://www.spaceaholic.com/lunar_module_saturn_v.htm . Please feel free to reference the material on my site if you think it will enhance this article on the LVDC.

Existing links to NASA reports are dead, and I wasn't able to find them on the NTRS. From http://www.sti.nasa.gov/find-sti/ [30 Nov 2013]: "On March 20, 2013, the NASA Administrator directed that the NASA Technical Reports Server (NTRS) be taken off-line while the Agency conducted a review of whether there is a risk of export-controlled documents being made available on the NTRS website.". For more info regading where this comes from go to [[1]]. Not sure why they bothered since the military of just about every capable nation on earth likely scraped the entire NTRS years ago. Here's one interesting report I was able to track down: Saturn V Apollo Launch Operations Plan [[2]] 203.129.23.146 (talk) 23:14, 29 November 2013 (UTC)
