HP Calculator Emulators for the Commodore 64 and ATARI 800XL - Craig Bladow - 01-03-2020 04:37 AM 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: http://members.aon.at/nkehrer/a800_c64_hp_emu.html I'm very impressed with the HP-45 emulator I'm running on a real Commodore 64 at the moment.

Cool emulators for a cool computer ;-) Tobie RE: HP Calculator Emulators for the Commodore 64 and ATARI 800XL - Dave Britten - 01-03-2020 01:28 PM That's a pretty interesting find. I'll have to put these on my Pi1541 sometime. RE: HP Calculator Emulators for the Commodore 64 and ATARI 800XL - TomC - 01-03-2020 01:49 PM AWEsome!!!

RE: HP Calculator Emulators for the Commodore 64 and ATARI 800XL - grsbanks - 01-03-2020 03:53 PM Brilliant -- the HP 35 emulator even has the e^(ln(2.02))=2 bug Using them with VICE: http://vice-emu.sourceforge.net/ RE: HP Calculator Emulators for the Commodore 64 and ATARI 800XL - Dave Britten - 02-16-2020 01:48 AM 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.

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? |
