**WRONG**  The V20 is a replacement for the 8088.  The V30 is the
replacement for the 8086.  V20/8088 uses 8-bit bus, V30/8086 uses 16.
This replacement is commonly done in AT&T 6300 PCs, and it supposedly
makes major speedups in Microslow Windows and s few other programs,
particularly those that do lots of integer math.

There are a few compatibility problems, caused by the upgraded
instruction set.  It seems some programs want to know whether they're
running on a PC or AT, so they try a few 80286 instructions  to see
what happens.  Well, the V30 can do those instructions, so the program
decides it's on an AT, and goes of into limbo-land because it isn't.
The major offendor is the driver for an AT&T expansion memory board.
Other than that, you're ok, and if it doesn't work you've only spent $20.
