- There have been several posts regarding hp48SX won't recongnize
- the RAM card. (TDS 512K RAM card, I think). I heard people told me
- that TDS and CMT's card are suppose to be 100% compatiable with
- the hp48SX. So is this just a special case or there are other
- users who have RAM card made by companies other than HP having
- the same problem? The reason I ask is that I am about to buy
- a CMT 128K RAM card for it's cheapest price in Educlac (only $80).
- 2nd, how does the display intensty setting affects the
- battery? I mean, if I put my calc to a darker intensity, would it
- use more power? (Yeah, call me a scrooge since I always try to
- use the lightest display to saving power, and now I am near-sighted:)
- Last thing. does anyone knows a way to "remove" a directory
- inside/outside to/from another directory? Like if I have home/math/draw,
- would it be possble to remove the draw directory to home directory?
- Hey, guess what? I just tested it by do "left-shift+dirname", which
- gives methe contents of the dir, then do "'dirname'", which gives me the
- name of the dir, I switch to the the appropriate directory, then "STO", and
- it's there! However, this is more like copy instead of remove. so incase
- I want to move a 10k directory it would be messy and I might run out of
- space.....so does anyone konws a way or is there're any program out
- there that does remove operation like in DOS?
- All responses would be greatly appricated. Thanks in advance!

- Later!

- PS: anyway you can get all 3 solutions at once when you try
- to solve a 3rd power equation such as x^3+7X-20X=0? I know you can
- graph the equation and find roots, or make different guess each tim
- in SOLVR to get different root. But is there a way to get all roots
- come out at once? (Oh, now I miss the TI-85.....it displays every
- root:)
