Re: HP-33s variable programming Message #5 Posted by Norris on 24 Oct 2004, 9:01 p.m., in response to message #3 by Michel
If you want an HP calculator with powerful programming capabilities, then you should get a 48 or 49 series model. These can do everything that a 41 can do, plus a whole lot more. However, the programming language (RPL) is more complex than that used on the 41, and the documentation may not be as helpful.
The 33S is not intended to be comparable to the high-end 41, 48, or 49; it is an inexpensive low-end model. The 33S is a redesigned version of the older 32S and 32SII. These models had only 384 bytes of memory, so they weren't intended for serious programming. The 33S has much more memory, but it inherited the same limited number of variable names and labels as the 32S and 32SII. Apparently it was easy to add a larger memory chip, but hard to overhaul the firmware for more variables and labels.
I don't think the 33S can be hacked. The 32S and 32SII have the same architecture as the 33S, have been around since 1988, and have not been hacked.
