Hmmm, thought I just said that. One of the more

improvements in the V20/V30 was the implemenation of dual internal data
busses. In practice, I don't know if it made a huge difference in speed,
but NEC claimed up to a 30% improvement for som operations..
That was a long time ago ... the XT clone wars. Back then a M$ mouse $100.
No need to gouge the public with windows /85 :)
I thought it interesting that the 8080 emulation of the
V20/V30 emulated
the Intel 8080A and not tne NEC 8080A instruction set.
So what instructions did the NEC 8080A have different?
