- XT's are ridiculous for running modern software (Mathematica,
- Derive). 286's are sometimes OK if you don't mind waiting awhile
- and don't need to use the machine that often. I think it's a
- disservice to recommend anything less than a 386SX to someone
- trying to do serious engineering or science work, though.
- Typically "cheap" 386SX boxes with hard drives and monitors go for
- about $1K. And these really are CHEAP PCs -- flimsy keyboards,
- huge dot pitch monitors, etc. Definitely not HP (or even TI or
- Casio) quality! Also, software for that PC of yours is going to
- run you at least another $100 for MathCAD, Mathematica, etc. -- and
- those are often the student versions.
-
- You think the high dot pitch monitors are worse than the 8 line hp48 display?
- Actually, I use a cheap Hercules-type monochrome monitor on my 486 box
- and find it adequate. I went to the store last week and tried a bunch
- of different keyboards and bought the BEST one I tried (for key feel
- etc.) It cost $25, which was also close to the cheapest. Generally
- all the really low quality stuff has been shaken out of the market
- by now. Even the cheapest stuff is usually to be pretty useable.
-
- According to the computer rag I'm looking at (Bay Area Computer
- Currents, Dec 1 1992), a 386sx-33 system with 1 meg ram, 40 meg disk
- and mono monitor is $490. (16 or 25 mhz cpu is very slightly less).
- This should suffice to run Jacal, a free symbolic math system that you
- can ftp from MIT (but I haven't tried it). You could also run the free
- Emacs calculator which is supposed to be comparable to an HP48, though
- you probably want to add at some more ram for this ($25/meg). (I've
- used that program, it's amazing).

-
- I think you're projecting what _you_ found adequate onto "nearly any
- student." Given that I have a HP-48 that I use regularily, I'd feel
- extremely constrained if I could _only_ use a 42S. (I do also own a 32S-II
- which I use a lot, though.)
-
- This might be true. But I took lots of math, physics, CS, and
- engineering classes, and don't think my experiences were atypical.
- I'm interested to hear what you do with your 48 that you couldn't
- do with your 32S-II (not sure what that is).
