Decoding newer serial numbers Message #1 Posted by Holger Weihe on 7 Feb 2003, 8:21 a.m. Hello, I have a HP-20S with the serial number ID83807111. This is not the numbering scheme of most other HP calculators. I think that "ID" stands for Indonesia. But in which year has this machine been produced? 83 would be to early, so maybe does the 8 mean 1988 or 1998? Anyone knows how to interpret this number? Holger
