I have an A2088 bridgeboard. Someone told me that if I took
out the Intel 8088 chip from the BB, and replace it with
a NEC V20 chip (5 MHz), the board would increase its 
speed a little bit. 
   I got two V20 chips mail order, and neither worked. When
I plug in the V20, the BB boots, but it reports that there
is an error in a 64K RAM address. After that, the entire
system freezes.  When I replaced the Intel 8088, everything
ran OK.
Anyone knows the cause of this problem?
(My bridgeboard has the old (1988) Janus chips and software).
Also, I noted that the chip number of my V20s is D70108D-5, 
while the chip number on a catalog is D70108C-5. 
Thanx in advance.
-Chris
