It is simply a bus, plus power. They implement the CPU on a card allowing you (for example) to upgrade from a 286 to 386 just by adding a processor. Typcially in the larger 386 systems, memory is hooked in via a daughter board or ribbon cable to avoid delay of access of the AT bus. This might be the way to go in developing a low cost hobbyist machine. It does allow access to a large number of very low cost cards. You can have a 10 or 12 slot bus and just plug whatever you want into it. -- Stuart.Lynne@wimsey.bc.ca uunet!van-bc!sl 604-937-7532(voice) 604-939-4768(fax)
