GATEWAY-48 I have written a code-lock program for the HP48SX with the following features: - Security. There are only two ways to start the calculator when GATEWAY-48 is enabled. Either you key in the correct 4-digit code, or you take out the batteries and wait until the calculator memory is empty! - Easy to use. Everything you need is contained in one library which installs itself. A function is provided which uninstalls GATEWAY-48. The OFF key can easily be redefined. - Versatility. You can change the code as often as you like. A personal startup message is possible ie "Belongs to XXYY" I need help to test this program before I release it! If you are not afraid of memory lost and would like to help me with this, please send me a mail. State the version of your HP48SX in the mail. Thank You! Erik Bryntse / SHPRF erikmb@cd.chalmers.se

Hey, I'd like to help you out on this one! My name is David Marsh, and you can reach me by voice telephone (714)568-5315. Please call in the evening (Pacific Standard Time). I have a rev 'E' machine with both sizes of RAM and ROM cards, and I have been having a few ideas on this subject myself...

Sounds like fun, I wouldn't mind being one of your testers, since I need
this kind of a program myself.

If you need any more testers count me in, I have a Rev 'E' model and
I would be willing to test what ever you have.

First of all, I wouldn't call it "hard" since it doesn't destroy anything - ON-A-F can be much "harder". ox{{ Second, codelock program has been verified not to let {i{{kO user in even if he uses back-reset-button.

>Or maybe taking out the top left(from the back) HP48 rubber foot, and >sticking a pin in the >hole to do a "hard" reset. ... I wouldn't call it a "hard" reset, more like a defibrillator port. When the calculator's heart starts spazzing out, you can stick a ThinkJet repriming tool in this hole to restore the heart's natural rhythm without amnesia (usually). I don't speak for HP.

Sorry for the interruption, but I seemed to miss the original posting
of this program due to the holiday and my system's short expire times.
Would somebody please mail me a copy? Thanks.

I wasn't aware that amnesia is a common complication of cardiac fibrillation. But that's not important right now... As far as I am concerned, the canonical reset doodah is a straightened-out paper-clip. ThinkJet repriming tool indeed. It'll be on the corporate price list next: HP 82237A HP 48SX de-spazzing tool $9.95 (pack of 3) HP 82237AF HP 48SX de-spazzing tool (Spanish documentation) $9.95 (pack of 3) HP 82238A HP 48SX de-spazzing toolkit (wallet+5 tools) $29.95 Option 001 deletes the tools -$9.95 Option 010 adds mustard (oops, sorry, wrong HP price list) After all, if people will pay $2.50 for a zip-lock bag, who knows what they'll pay for a precision-engineered piece of wire? -- Frank Wales, Grep Limited, [frank@grep.co.uk<->uunet!grep!frank] Kirkfields Business Centre, Kirk Lane, LEEDS, UK, LS19 7LX.

I always wondered why HP didn't include a molded-in holder for a paper clip, since it was extremely useful. I haven't had to defib my Rev.A HP-48SX yet. Either I'm lucky, or careful, or I know all the tricks. I vote for (a) or (b). regards to Frank Ray address & disclaimer on file elsewhere

Hi, I'm curious about how you disabled the ON-A-F key sequence. Could you please pass me on some details as to how you accomplished this? I am also willing to try your program out on my Version D.
