After not succeeding in sourcing a copy of ETKA, I've just managed to buy this for the tidy sum of £1.04 on eBay +99p for postage so happy with that one! 
If you need a hand, I can probably give you some pointers. I'm running it on VMWare on a Mac Book Pro and am having to run a Windows XP emulator in a Windows 7 Professional environment. So, an emulator in an emulator. Why they can't revise the code base to make it run on a reasonably modern machine is just annoying.
Would it not be easier to run a dual boot of xp and mac osx using boot camp, thats what i did for my ford dreamscience software, you can spec a dual boot partition from as little as 5GB which isnt much at all really.
Booting into xp then is just a case of resetting the mac and holding the option key to select which os you want to boot to.
