Full Version: 33s initial impressions

Just bought two HP33s'. It seems like a pretty nice calculator so far.

Compared to the 49g+, I'm very glad that I can fire off strings of numbers w/o missing any. IRT the complaints about how 26 LBLs' won't stretch to 31k, but...I'll use it to organize equation sets, for example:

X-SECT PROP
i-beam(wide)
i=w*(d^3)/....
circ tube
i=pi*(sq(b)-sq....
BEAM DEFLECT
pt load at a
d=pl^3/(3EI)

and so on..
Also, I was unaware that branching, conditional programming structures were supported. Size of case is ok as well.

Yes, the 33S is a capable calculator, based on the 32SII of 1991, which in turn was based on the 32S of 1988. The 31kB of RAM allows the user to retain a library of equations and programs.

Quite frankly, though, I would have been much more pleased with a RPN-only 32SII with 8 kB RAM and complete complex-number functionality.

Sounds like a 42S... :-)

How do you plan to get around the limits of 26 labels?

I've found that, like you, equation sets is the way to go - partly, though organizing them and parsing through the (so far) 80 equations I've kept is tedious.

Yes, those are two attributes of the 42S, but what I suggested was still quite different:

  • No matrix functions
  • No named variables
  • No character strings
  • no numbered registers
  • No IR output
  • No bit-wise logical operations
  • Simpler (but less capable) programming
  • One-line (but much more legible) display
