This is the best series of posts on EEVBLOG! Very informative, and interesting. My 2467B is on it's way from NYC off ebay. Cannot read SN well, but looks to be starting 05, so probably has the Dallas. Cannot quite read what is showing on the CRT either, so unknown if it has error messages. Seller did not seem to really know much. I figured out from the fuzzy rear photo that it has Option 05 TV Sync Sep, Option 06 CTT, Option 11 Probe Power. Can't wait to get it, open it, and see what's up... leaning toward the big battery option for the Dallas.
