Thanks to Joe Horn's HHC2007 website, now we've got a very up close and personal view of the HP 35s (1119x2054 pixels!)

After a long time of HP49G+/HP48GII/HP33S/.../HP50G uglyness, I must admit that I actually like this one very much ... Edited: 10 July 2007, 5:04 a.m.

Thanks for the picture! It does look nice! It's just a pity that it is not switched on! It would be interesting to see the working display. I just wonder why HP designers / technicians are unable to make the difference between left / right, top / bottom ...

Quote: Yes, I'm curious to see what the exponent display is like. HP have done some shockers in this area, like the 20S with it's large "E" which blends in very nicely with the other digits, you have to study the display closely to see if your answer has an exponent or not. Dave. ▼

Quote: There's no reason to expect it to be different from the HP33S display, with its individual dotmatrix characters. As for the fullsize "E" denoting a base10 exponent on the HP20S and HP21S: With a uniform 12digit 7segment display, that was the only reasonable approach other than the one employed on all previous models, which was to rightjustify the (twodigit) exponent on a 10digit display. "1.234567E123" was deemed preferable to "1.234567 123" or "1.2345678123". Not all would agree. The original HP32S also used a fullsize "E" and centered exponent sign, even though it had a moreversatile dotmatrix character display. Two small refinements were provided in the HP32SII: A reducedsize "E", as well as a raised negativeexponent sign to distiguish it from a minus sign used in equations.  KS

I certainly don't agree. That, and the fact that there is no dedicated exponent key are my only two gripes with the 20S. All the same I currently use it as my daily calc at work. Dave. ▼

Quote: I agree with you that "1.234E5" is not very legible on 7segment displays; I preferred the original method (used on all 10digit models) of one or more blank characters separating the mantissa and the exponent, with an exponent minussign occupying one of those separators. Perhaps the intent for the Pioneer series was to utilize that generallyunderstood display method of Fortran, C, and other languages to represent exponentiated numbers using an "E". This was certainly reasonable for the midgrade and highend Pioneers featuring dotmatrix displays, so it was simpler to do the same for the lowend Pioneers (HP10B, HP20S, and HP21S) with their 7segment displays. However, "1.234E5" is more legible in standard alphanumeric fonts than in 7segment displays, due to curvature of the numerals. Also, a display utilizing spaces between a mantissa and exponent would be impractical for compiled code, because of difficulty in parsing. Casio models typically display an exponent using two smaller, elevated digits at the far right of the display. This renders some of the display space unavailable, however.  KS ▼

Dave commented on the problem with the 12.34E5 convention for the case when the exponent is positive (12.34E5). I'd suggest the simple (edited out: simply) and uniform solution would be to use this: 12.34E+5 for positive exp 12.34E5 for negative exp This is the convention followed in some engineering packages that I use/used.

Yep, no problems with that. It visually breaks up the exponent nicely. Dave.

Quote: Yes "E" is a perfectly normal and excepted way to represent an exponent, no problems there. But it should never be used on a 7 segment display unless there is a space before the "E", but then you waste an extra digit. I prefer the Casio displays, having the exponent as smaller raised digits. Very sensible and very obvious to look at a glance. I do like the raised and centered "E" on the 42S though. In fact I much prefer the fixed location of an exponent with the digits filling up right to left as on the Casios. I've always thought the lefttoright display which HP uses to be not as good. It means your attention is always darting back and forth around the screen which I find a tad more annoying. Dave.

Quote: I very much agree. Just one thing that could have made it nicer, and an added nod to the original 35: if the name HewlettPackard, the model number and the HP logo had been on the bottomfront edge of the machine. That would have been so nice! Best

For readers in Germany: There is no definite release date for the HP35s in Germany so far (official statement of HP today). More information may be available in September. For the time until then, some folks in the internet may make a bit more ;)

Just wondering if it will be possible to connect the HP35s to PC in order to save/load programs. Apologize that I did not read the HP35s specification carefully. May we expect the same problem as with the HP42s (a powerful machine, with very limited means for entering a program, i.e. keyboard only)?
