HP-45 Message #1 Posted by Jon on 2 Sept 2003, 6:58 p.m. I have got a HP-45 and I see the model is not written in the front label (just hewlett packard). Is this usual?. I canīt use the timer facility (RCL CHS 7 8). Are there calculators without it?. Thanks Jon

Re: HP-45 Timer Missing? Message #4 Posted by Katie on 4 Sept 2003, 12:48 a.m., in response to message #1 by Jon Supposedly the later models of the 45 don't have the timer in ROM. What's the serial number on yours? The most recent one that I have is 1350Axxxxx and it has the timer in there.

Sorry,the timer is present Message #5 Posted by Jon on 4 Sept 2003, 2:50 p.m., in response to message #4 by Katie The timer works. I was doing it wrong, sorry. I was pushing all the keys at the same time. When I push RCL and after CHS-7-8 it works. In the other hand I insist, it is a HP-45 and the model doesnīt appear in the front label :-)

Re: HP-45 Timer Missing? Message #6 Posted by David Smith on 4 Sept 2003, 5:59 p.m., in response to message #4 by Katie I have never seen an HP-45 without the timer function, and I have played with some very late model ones. I would suspect that your machine either has had the front label replaced from a '35 or an old style label was left hanging around in the HP parts bin and was used when the machine was built. I have seen quite a few flukes like this (particularly very early in the production cycle) like HP25C machines with HP25 front labels, or keyboards that did not have "Continuous Memory". I also have an HP25 with an HP22 front label (known to have come that way from the factory).

SERIAL NUMBER Message #7 Posted by Jon on 5 Sept 2003, 12:56 p.m., in response to message #6 by David Smith May be somebody is interested on the serial number. It is 1507S06263
