new HP35

The key layout is far better. A screwdriver is often better tool choice than a hammer.

They're great for repetitive calculations, but no so much for a one-off. Though I use them all the time, a lot of engineering calculations are a PITA on a spreadsheet.

I even use resistors on boards. ;-)

I almost always have a pad of paper and a calculator sitting next to my keyboard.

It's because a calculator is faster and more convenient. You can move it around your desk, sit it on the datasheet or catalog you are working with, take it anywhere like the next cubicle, lab, meeting etc etc. And it always works when you need it, no modes, no boot or load time, and solar powered ones never run out of juice. Computer based calculators have none of these advantages, and similar with phone based calculators.

Fractions can be entered using the space key. Calculations will be done returning fractions where possible.

Agree about the binary modes. OTOH, the HP15C (not 16C) that I was replacing didn't have any binary modes at all.

Your point?

Maybe not readily available in Aus. But IIRC my dad had an HP35 then an HP45 well before i graduated HS in 1970.

I never found changing newsreaders to be that big of a issue. I have several installed and can (and occasionally do) use any of them. I prefer agent.

Shame on you Jim, you could have found out he is using Thunderbird for the cost of one keystroke.

Was there a big improvement in filtering capability in 6. Not that i have been really trying but that kind of discernment does not seem to be available in 5.

Two things, it is intractable in linux/wine and Agent is far better.

You've got it, dumbhead protection techniques aren't worth the time and cost to implement them. And really effective ones either interfere with normal use way too much or piss away all the company money on hiring several brigades of IT soldiers.

Ummm, no. The HP 45 introduced the programming mode.

I knew what he was using. I was just stickin' it to 'im ;-) ...Jim Thompson

I see no big differences from 5 to 6, 4 to 5 was the important filtering jump. I pay for upgrades... good programming needs its rewards... and they listen to my suggestions ;-) ...Jim Thompson

OK, one "computation" mode. "Computation" vs. "programming" are so fundamentally different than I can forgive them for that, particularly when they were cranking these things out back in the '70s with very limited CPU and memory resources. :-)

The RPL machines (HP-28/38/48/50/etc.) arguably are completely unified (programs are objects just like numbers).

But that point was that even today Casio and Sharp machines have separate modes for matrix math, table creation, complex numbers, statistics, and regular old "number crunching." Typically programs or memories stored in one mode don't work (or aren't accessible) in the others.

Nope. The HP35 was announced in the summer of 1972 and the HP45 in

I meant binary fractional arithmetic is missing.

The binary functions are next to useless without binary fractions. I've only found one RPN calculator with a useful binary mode and that's a Palm app.

With my HP11C I can find out in under 5 seconds where something might resonate. With a PC I can only do that if I have the proper formula entered into a spreadsheet. Which also needs to be open, no time to wait for some program to load.

That's pretty useless when you are at a client in the lab, the table is full of stuff and the next computer is over yonder in a corner, with someone whom you don't know sitting in front of it. "Hey, dude, could you let me have your PC for a minute?"
