Your | Henry Spencer at U of Toronto Zoology -passport and visa, comrade? | uunet!attcan!utzoo!henry henry@zoo.toronto.edu Has anyone ever interfaced a PC peripheral with a PC bus connector to anything other than a 80X86 motherboard? To follow Henry's idea is to simply build another PC clone in my estimation. And to be perfectly honest why build another PC clone when you can buy one cheaper. I think the motherboard physical sizing is a good idea but to conform to PC bus elcetrical specs is a cop out. Yes my anit-Intel bias is showing...
