Not all clones can use the V20.  I am the proud (?) owner of a "Standard
Brand" PC/XT clone from CompuAdd.  I tried a V20 in it and got all sorts of
weird error messages.  The same V20 chip works like a champ in a real PC,
but the "Standard Brand" clone works only with the supplied INTEL 8088.
The board layout is enough different from a PC that the Microsync d-Clock
won't work in it, either.  Compatible?  Well ...
