I am looking for a programmable handheld that has an internal time-of-day clock that permits the current time to be retrieved as a value by programs. Currently, I know of three handhelds that permit this: the SHARP PC-1500, the HP-17B, and HP-48. None of these are entirely satisfactory. The SHARP PC-1500 is no longer in production, and is hard to find used. In addition, it's BASIC interpreter is very slow. The HP-17B has only limited scientific programming capabilities, being a business calculator, and the HP-48 is simply too expensive for me. (I'd like something <= $100.) Does anybody know of some other programmable handhelds that feature internal time-of-day clocks? (Regardless of the price?) I assume that the Atari Portfolio has one that can be accessed by programs, but am not sure? Are there others by Casio? TI? -- Kenneth B.

The HP28 does not have a time-of-day clock built-in by default, but it does have an internal timer that people have used to base clocks around. Back when I had my 28S I had one of these programs and it seemed to keep pretty good time. Anyway, the 28S is available used from Edu-Calc for under $100, and i'm sure one of the HP archives has the clock program(which i'm sure could be modified to return the current time when called by another program) Ken Rawlings > > >-- >Kenneth B.

You can also read the internal clock on a HP-28s. (This is not stated in the manuals) It is much cheaper than a HP-48. Note: Before I get flooded with mail from HP-28s users who didn't know this let me say that all of the information is available from my mail server. mail To: wscott@ecn.purdue.edu Subject: HP-MAIL-SERVER HP28 send INDEX . -- _________________________________________________________________________ Wayne Scott | INTERNET: wscott@ecn.purdue.edu Electrical Engineering | BITNET: wscott%ecn.purdue.edu@purccvm Purdue University | UUCP: purdue, pur-ee}!ecn.purdue.edu!wscott

They can be had used for under $100, and while they are out of production, is still a very popular machine. >Kenneth B.

Not <=$100, but close: US$135 from EduCalc. The HP19B has all of the date and time capabilities of the HP17B, plus a comprehensive range of scientific and math functions., and business functions. Like the HP17B, the HP19B programmability is via the HP SOLVE capabilities. The final choice of calculator depends on the type of problems to be solved, but in any case, the HP19BII is worth serious consideration!

Another calculator which allows programs to get the time, and which costs less than $100 is the HP27S. This is in many ways like the HP17B, which the questioner did not want because of its lack of scientific functions, but the 27S has more scientific functions than the 17B, and fewer business functions. In fact both are subsets of the 19B, which also has time functions (but costs well over $100), except that the 27S also has a BASE menu for hex, dec, oct, binary numbers, and has ten alarms instead of five. Are there any other folks out there who would like to see an updated HP 27S with RPN - the way the HP 19B and HP 17B have been updated to the HP Are there people out there who would agree with me that an HP 27S with RPN, like the HP 19BII and the HP 17BII would be nice?

Yes, I think that an RPN "HP-27SII" would be a very nice machine, certainly *much* improved over the 32S... Craig A.
