| "pfjw@aol.com" <peterwieck33@gmail.com>: Dec 21 09:56AM -0800 Some SWAGs here. When I came up, the surveyors I was around pretty much hated self-leveling devices. "How do you know?" was their call. Today, it is all data points and GPS loaded into a self-everything transit. http://sokkisha.jp/level.html Is a link in Janglish, but readable enough. It has an exploded diagram and points out several leveling screws. It would seem to me that the key is getting the base completely level (dial mike?), then adjusting the eyepiece to fixed level points. Good luck with it. These old devices can still be useful.

This could well be 1963 vintage, the serial number ends 63. The GPS people have done a great job at convincing people its soooo accurate, despite 30 to 50 "corrections" routinely included. Local archaeologists stopped using GPS, including dGPS, for initial site positioning, using it only on site. For a site fundamental reference they pay Ordnance Survey 20 GBP for data on a nearby benchmark or feature on an old/protected building. They had so many problems with wrong GPS data over the years. |
| N_Cook <diverse@tcp.co.uk>: Dec 21 06:33PM From the exploded view there, the 4 set screws (2 shown there) must adjust the reticule/crosswires, less problematic than some part of the optics sytsem I assume, makes me a bit more confident. |
| N_Cook <diverse@tcp.co.uk>: Dec 22 08:56AM A technical manual for different make but something similar http://www.redtailrental.com/assets/upload/Level%20-%20Manual.pdf Diagram M, shows similar removable cover to expose cross-hair adjusters, 4 + 1 for this one. If weather stays up, off to the lake again today , set up a pair of staffs wrt to the lake surface and try adjusting to <>0 |

I'm pretty sure there are some e.g. video game systems where the language is such that simply by opening the box and using the product you wave all reverse engineering rights to extracting, de-compiling, or modifying the hardware or software. LTSpice's EULA for example prohibits "de-compiling or modifying" their binaries or device models, whether that includes somehow decrypting their just-encrypted device models to examine them I don't know, the act of simply de-crypting a file isn't decompiling anything and you're not modifying the model itself. |

To what degree any of that is actually Constitutional I'm not sure either, the NFL seems to have for a long time been getting away with putting language in their telecasts and ticket sales that it's against your "user contract" to even publish a written description of events you saw with your own eyes on an NFL TV broadcast or at an NFL game. |

Hi, sorry for the delay in my reply. Probably related to my experience in Missile Command, After Burner 2, Outrun, Sonic The Hedgehog, Super Mario Brothers, etc. 1983 - 1995 |
