Could you people give at least a warning that doing the above requires the RESET. I, like any good hacker, tried this on my Rev A 48SX.... Then I pressed DROP/CLEAR and it started beeping and flashing the display - I nearly dropped it ;-) Another thing, one that worries me, after going through the RAM0 and RAM1 tests, my HP reports a "FAIL 00180"... hmmm... is this something to worry about or is this normal (hey, you never know) (by the way, I just got this HP a few weeks ago and have used it a little) (I think anyone who posts stuff like above either needs a disclaimer or instructions on how to reset the calculator - in their signature ... :-) >John Hawkinson >jhawk@panix.uucp Take care.
