Emulator CPU usage Message #1 Posted by Martin Pinckney on 9 Oct 2010, 10:02 p.m. I've noticed that when the 41c emulator by Harassed Programmer is active, the CPU usage meter on my laptop stays over 50%. By comparison, with the Emu48 by Christoph GieBelink it may be only around 5%. Has anyone else observed such behavior? Why such heavy demands from such a small program? I have an HP TC4400 running Windows 7 Professional.

Re: Emulator CPU usage Message #3 Posted by HrastProgrammer on 11 Oct 2010, 11:07 a.m., in response to message #1 by Martin Pinckney Quote: Harassed Programmer LOL^2 ... "Harassed" (= "To irritate or torment persistently") I should probably don't bother to answer but anyway ... My HP-41E for Windows is very old program and some parts of it could be coded much better, going to sleep while waiting for a key, for example. But I used it only as a test/development platform for my emulators running on HP-48GX/49G, so I didn't bother to fix it. Use V41 by Warren Furlow, it is much better. As far as I can remember, link to his site should not be posted here, but you can Google for it ... Best regards. Harassed Programmer

Re: Emulator CPU usage Message #4 Posted by Martin Pinckney on 11 Oct 2010, 3:49 p.m., in response to message #3 by HrastProgrammer No, actually I do appreciate your answering... and not taking offense at my little joke. I was, of course, referring to your FAQ's which suggest to me that you are often Harassed by folks expecting free software...

Re: Emulator CPU usage Message #5 Posted by HrastProgrammer on 12 Oct 2010, 1:37 a.m., in response to message #4 by Martin Pinckney No problem, I didn't recognize it's a joke, sorry. I never said in my FAQ that I am "harassed" by people expecting free software, just that (1) not all of my emulators will be free and (2) none of my software will be open-sourced because I don't like open-source concept, nothing else. BTW, I restored HP-41E source from the archive (it's the latest version, I think, v1.02 from 2001) and fixed this annoying CPU usage issue.
