Interesting 41C customization Message #1 Posted by Katie on 29 Dec 2004, 1:25 a.m. Here's what appears to be a highly customized 41C(V/X?) for surveying that I've never run across before: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=26204&item=3863570706&rd=1 (Unfortunately the calculator itself is not included in the auction, but it's shown.) Do serious 41 collectors know about this?

Re: Interesting 41C customization Message #2 Posted by Diego Diaz on 29 Dec 2004, 8:21 a.m., in response to message #1 by Katie Hi Katie, There is little info on such devices available. AFAIK these data collector units were developed by a Swedish company (Geotronics), Geodat-126 and Geodat-400, 500 & 600 series. Surprisingly the 400 holds 900 points while 126 holds 1.500 points. The waterproof shell-like enclosure shown in the auction is equiped with an HP-IL inteface (82160A) and a proprietary serial adapter wich identifies itself on the loop as Device #78 [AID] named "GDAT 126" [ID]. I've got the 126 enclosure, and would like to know if someone out there has got a full working unit... Best wishes Diego
