Several weeks ago I posted a request for information on upgrading an
AT&T PC6300 by replacing the 8086 with a NEC V-30. I promised a
folowup (for those who aren't sick to death of the subject), so here
it is.
Thanks to all who replied -- especially to Rob Stampfli who had
posted a similar request several months prior to mine.

The questions and a summary of the responses:
>1. What sort of performance increase should one expect?
Claims for performance increase were consistently in the 10-20%
range. Norton's SI index showed an increase from 1.9 to
about 3.5. One person reported an SI of 4.2 after the V-30
installation.
>2. Is a ROM upgrade for older 6300's necessary?
No, the V-30 worked fine with versions 1.21 and 1.43 ROM.
>3. Any other gotchas to be wary of?
Some games would not run, but there was conflicting information on
that point. Most people reported NO problems with software.
Apparently the V-30 will not work with AT&T's extended memory card.
This is the ONLY reported hardware problem.
