A common PC is a layered monstrosity that can still run nearly every desktop OS made since the early 80's. I would not surprised if every modern chipset had a vestigial cassette port lurking in there for when you wrote "CLOAD" on GWBASIC.<p>I see no reason for a modern x86 (Oh God... What am I saying) to be able to faithfully run code targeted for the 8088. Heck... I am not sure if there is any reason to even support 487 instructions...
