Yes :). Some of your questions are answered by this table I compiled: This was based on running ca. 30 positions on each platform for ca. 4.5 minutes each (my test protocol isn't on my hard drive at the moment, so I'm a bit vague.) ========================================================== HIARCS 7 - with 64Mb Hash (Mac) or 63Mb Hash (PC) Machine CPU MHz CPU Nodes/second nps/MHz Configuration =================================================================== Mac Yosemite 400 MHz 750 53,413 nps 133.5 Sys 8.5.1, 128Mb RAM, G3 Mac Yosemite 350 MHz 750 47,615 nps 136.0 Sys 8.5.1, 128Mb RAM, G3 Mac PowerBook 300 MHz 750 40,062 nps 133.5 Sys 8.5, 192Mb RAM, G3 Mac ??? 310 MHz 750 38,929 nps 125.6 Sys 8.1, accel. card?

It works fine for me on 8.6, 8.5.1, 8.5, 8.1 and 7.5. I've never tried 9. >(b) Do Fritz 6.0 and Hiarcs 70 for PC work on Virtual PC? If so, what version >of Windows would be recommended?

At the same MHz, Hiarcs runs faster on G3s than any Intel-compatible chip I have data for.
