Somebody brought up an interesting claim and I'd like to hear from you S7T emulator users about it. The claim was in reference to the energy usage of an emulated System 7 environment on a host system versus using modern native software. If I got it right, the claim was that an emulated System 7 running graphics software will last decisively longer on a laptop battery than using it's native (but bloated) modern software. For example, GIMP or Photoshop. Because modern software is so resource intensive even for just basic things. The point was that you can get the same results with low-tech stuff, and at a much lower price / energy impact. Can somebody from the emulator camp confirm that claim? |

while i cant say much for energy usage under a very early 2001 build of vMac 0.19c on a Dell Lattitude C600 running Windows ME i get maybe more minutes using mini vmac and not any other app EDIT forgot the # of minutes 23 to be exact

Intriguing thought!  I'll monitor my emulator usage on my laptop, tablet and phone and report anything that might confirm this observation

Modern electronics have gotten very energy efficient. I am running Sonoma on the last gen intel MacBook Pro and for day to day usage It lasts 6+ hours on a charge. Emulating Mac OS 9 using UTM/QEMU has no more impact than any other application I might run. The Mac OS puts UTM to sleep whenever it goes into the background so it is using almost nothing. Running it in the foreground shows it using 1-3% of the total system usage. The SheepShaver emulator is a huge energy hog whether it is in the background of the foreground it uses 14-17% of the systems energy. So in my setup QEMU/UTM running OS 9 uses less energy than any other MacOS X application. Safari just being open uses about 3X more energy than QEMU uses doing work in the foreground. On the other hand SheepShaver running OS 9 is about the most energy intense application I have installed, whether I am actually using it, or it is simply running in the background. This is emulation running on MacOS X. I have no idea what kinds of results one would have with the emulation running under a different host OS.
