NatSemi QBUS 256KB memory card

So there is a National Semiconfuctor 256KB QBUS memory card which has a number of examples floating around for sale (e.g. eBay #370953707487), but which has heretofore been un-identified: the only numbers/names/etc on it are "PWB 551103882" and "PWA 980103882", which is what one usually finds them listed under. Well, it turns out that it's called an "NS23M", and a manual and print set for it, previously un-available online, are now available here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/NS23M.pdf Can people who maintain repositories (e.g. BitSavers) please include this in their sites? Sorry about the size of the file; the original scans were 300 dpi, which in retrospect was probably a bit more than needed, but rather than throw away resolution, I've left them in like that; repository maintainers may wish to reduce the page images in resolution somewhat, to make the file a bit smaller. And a very big 'Thank You' to Mr. Steve Burgess, who was nice enough to make scans of a manual in his possession, and send them to me. If anyone finds this manual useful, please make a small donation to a local animal charity! Noel
