Re: What age is this 35/2 Message #5 Posted by Jim L on 13 May 2001, 10:42 p.m., in response to message #4 by Scotty Pritchard
Scotty,
I think the critical bit from that page is:
"The correspondence of serial numbers to dates is only approximate. In some cases, they may be better indicators of the date of manufacture of the case or label rather than the entire calculator. With some desktop models, it appears that the date code was changed only when there were manufacturing changes. On the other hand, different versions of the HP-35 can be found with the same date code. (The museum has examples of type 3 and 4 with date code 1346 and some of the type 4s have lower sequence numbers than the type 3s!) "
Lower down the page you'll see that the lowest seen S/Ns for both type 1 and 2 are 1143.
