Norbert Kehrer was interviewed recently on the FloppyDays Vintage Computing Podcast, episode 96, by Randy Kindig. Where it was mentioned he wrote a series of HP calculator emulators (35,45,55,80) for the Commodore and Atari computers! You can read about them here:

I'm very impressed with the HP-45 emulator I'm running on a real Commodore 64 at the moment.
Thank you for this link. Cool emulators for a cool computer ;-)

That's a pretty interesting find. I'll have to put these on my Pi1541 sometime.

I'm loading them from a Pi1541 too!
I just had a chance to play around with the HP-55 emulator on my C64 tonight. The sharpness of the digits is outstanding with the new s-video cable I bought.
I typed in the direct reduction loan program from the 55 Mathematics book and calculated a payment amount.
Anybody benchmarked these against the real things yet? The 55 emulator seemed pretty responsive, but I don't have a real 55 to compare it with. I think the 80 has a few routines that take some time to execute (like solving for i%). Those might make good tests.

It might just be freaking out at the members.aon.at domain in general. Try it from here:

Hmmm, unlikely it's a C64 virus.
Google doesn't flag it, Sucuri.net gave it a passing grade. Maybe because its http and not https?
