Congratulations & little contest [Was: Re: 2637A31xxx]... Message #4 Posted by Raymond Del Tondo on 10 Apr 2003, 9:02 a.m., in response to message #2 by casey You won! Hmm, we could make a little conntest of lowest serial numbers. Below I mention my calcs with s/n equal or even earlier than in the museum list (http://www.hpmuseum.org/collect.htm#numbers): HP-17B: 2747A00651 HP-17B: 2801A00457 HP-20S: 2831A16267 HP-33E: 1814A13665 HP-35: 1302S50202 (T3, common s/n front part) HP-45: 1301S13542 (common s/n front part) HP-48SX: 3003A00131 HP-80: 1247A45830 (common s/n front part) Those with remark '(common s/n front part)' usually have printed date code, and a stamped 5-digit number after the country code. AFAIK all of those models have a printed date code, so here the rightmost five digits count. Regards, Raymond
