FOLLOWUP: NEC V-30 PC6300 upgrades.

[Mick Laver]

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.
