tacked on. I don't know how V-8086 handles "additions"
as it emulates a peecee on a windows box, but it at
least seems that you could "add" on the ancillary '186
functionality in the same way you add the other
components present on a peecee mobo.
Yes, you probably could. The big problem that I see is while the
386/486/Pentium V86 mode is close to what an 80186 does, there are
differences (itemized in the V86 mode description). They may not
make any difference, but if they do, you're out of luck.
Plus, setting up a V86 session is pretty involved. You need to have
a protected mode server for the V86 session and set up all of the
IDT/GDT/LDT stuff that goes along with it. It feels like a lot of
work to me, but I could be mistaken.
I'm assuming that you're going to host this thing on DOS; I don't
know what provisions for V86 mode are built into Linux (never had a
reason to look), but maybe that might be easier.
