You may try a mail order firm called EduCALC:
their address is 27953 Cabot Road,
                 Laguna Niguel, CA 92677
                 1-800-677-7001.
I am not affiliated in any ay to EduCALC, but I'm always been satisfied
with their service. They stock almost everything for HP calculators.

I can't say anything positive about that, but in my opinion the worst
that you could possibly do with a syseval is to lose the calculator
memory... I don't see how you could possibly damage the hardware!

I leave this to other netters... I own a 48sx-A and I have enough of the
bugs in it :)... [but thanks to HP i'm going to get an upgraded machine
soon!!!]
