|Deciphering a HP 48G Serial Number|
Message #1 Posted by Jeff Kearns on 25 Aug 2007, 6:06 p.m.
I recently came across an immaculate second-hand 48G on Craigslist and bought it (without manuals) for $40CDN. A nice addition to my modest collection! The serial number however, is non-standard: SG72704563. Beyond being made in Singapore, can anyone tell me when this unit was manufactured? Many thanks,

This serial number follows the post-1996 standard.
SG = Singapore.
7 = one-digit year code, 1997
27 = two-digit week code, 27th week of 1997
04563 = 4,563rd unit manufactured that week.
Interestingly, I thought that all manufacturing had moved to Indonesia by 1997. I guess not!
