Well, if it's any help, on my rev E unit with the 'coarse' temperature chip, there is a sticker on the top (near the power connector) with a bar code, a date (3/14/05) and the Rev E designation. There's also a series of numbers that could be a serial number and some other kind of rev designator but their significance is not clear.
My Rev D unit with the 'fine' temperature chip has a similar sticker dated 12/16/03. Paul - K9MR On Aug 10, 2011, at 5:55 PM, Richard W. Solomon wrote: OK, now, how old is old enough ?? Where is the units date code located ? Hopefully, the seller knows (or even cares) where to find it. 73, Dick, W1KSZ -----Original Message----- > From: Bob Camp <[email protected]> > Sent: Aug 10, 2011 9:59 AM > To: 'Discussion of precise time and frequency measurement' > <[email protected]> > Subject: Re: [time-nuts] Thunderbolt hardware revisions > > Hi > > The real question is what's the date code on the unit?
