Hardware is the user's private property and our software just 'leases' user's property. Remember and remember again -- the native hardware for Windows 95 is 386 with 8M(4 minimum) RAM and HD about 200-400M. So, if our *Win32* program doesn't want run on such the machine, we must say --- "ONLY for 486+Win98 and up" "ONLY for 586+Win2000 and up" --- just to avoid any questions on a matter of restrictions. If we say Win32 - this is 386+, just as *EXW.EXE* - EUPHORIA's Win32 platform without *ANY* restrictions on the *latest* hardware. My 386-25Mhz runs rotozoom.ex (by Mic) at 7 f/s when Mic's PII-450Mhz runs it at 70 f/s, and I can try and use really good and useful *Win32* software on my old good 386 without any problems. One my old friend uses 286-20Mhz 40M HD and Rob Zale's great TurboBasic for scientific tasks about 15 years and doesn't want ever hear about professional looking Win & Co. I have TV to see the best quality animated cartoons, he says. :) Just my point of view on hardware, sorry Bernie. Regards, Igor Kachan kinz at peterlink.ru
