If MS and IBM had skipped the 286 and written OS/3 instead, we would have had it long, long ago. The reason that it is so difficult is the slightly brain-damaged 286, which requires all sorts of tricks to be useful in this kind of app. For example, to switch from prot to real mode requires resetting the the processor. It was only designed to go from real to prot. You can't really blame Intel, the 286 hit the market about the time the PC and MS-DOS really got popular. Most of these problems are fixed in the 386. MS seems to be hinting that OS/2.386 will be out 1Q89. We'll see. That should greatly improve the performance of the penalty box, since the 386 has a real live working virtual 86 mode. ( see Windows386) IBMers wearing jeans???? Must have been Apple guys playing a joke. cris -- ||...despair! Despair I can handle, it's the hope...
