Very Interesting S/N Message #1 Posted by thebullcabinet on 15 July 2004, 1:44 a.m. I came across a 48GX with an S/N of ID14001100. I may have missed something, but I think 3322 is listed here as the lowest known non-proto number. Have I misunderstood something? Can anyone explain this number? Thanx.

Yours is a very recent unit from 2001, with the serial number schema which HP uses since the mid nineties. For serial number formats, please check on the appriorate subpage (from the main page) here in the museum. The link is her: http://www.hpmuseum.org/collect.htm#numbers Raymond

I always thought it was the start of 1997, however I recently purchased a NIB 48GX with serial number 3702SXXXXX. What's the earliest new-format S/N out there? Or alternatively, what's the oldest old-format S/N? B.

Re: Older S/N's Message #5 Posted by Randy Sloyer on 15 July 2004, 6:34 p.m., in response to message #4 by Scuba Diver 1997 Singapore SC710nnnnn and 1997 Indonesian ID703nnnnn are the earliest I have in that format. I think we can conclude there was concurrent production from the two sites. FWIW, the last Singapore date code I've recorded is SG730nnnnn, in the older format 3708Snnnnn, only two weeks difference of the new format.
