I have a few questions that haven't come up in discussion, so I'll
be bold and ask them:
What differences exist in the operation of the Microsoft mouses (mice?)
between the bus version and the serial version? Is the serial version
slower? the same? I am looking to purchase the serial version for port-
ability between machines, but don't wish to sacrifice utility.
Has anyone with a V-20 processor used an 8087 with it? Do they work
together without contention? What kind of speed advantage did you
find? I have become addicted to an 8 Mhz 8088/8087 but like the
idea of CP/M native code with the new patch programs. How well do
THEY work?
Just what ARE the differences between the Everex Edge and Graphics
Edge cards other than single/multiple display capability? I would
appreciate hearing from users of these two cards about their experiences
good/bad.
By the way, has anyone gotten Apple Turnover to work with any of the
Taiwan-made (cheapie) disk controller boards? If so, Which one(s).
Compaq owners beware - A.T. does NOT work with the Compaq.
'nuff said. Thanks in advance for the useful information.

I replaced the 8086 in my 8-MHz Fujitsu Micro-16s about 8 or 9 months ago with a V-30. The FJ box has an 8087, and runs MS-DOS (2.11). I have had *NO* problems whatsoever, nor any S/W that behaves differently (thankfully, none of my S/W relies on instruction cycle/timing loops). Overall, I see a performance improvement of about 15%, though programs that do alot of string manipulation are a bit better than this (say 20%). The V-30 has had no problem communicating with the 8087, though you will see very little of a performance improvement (if any) in any application that is 8087 intensive. Rumor has it that NEC is about ready to introduce an 8087-equivalent part that runs faster/cooler/etc., and has additional built-in functions, and other enhancements. I dunno how well the 8080 mode works out, as the FJ machine has a Z80 subbordinate processor that runs what little 8-bit code I have. There was an excellent 2-part article on this subject in Micro/Systems Journal earlier this year. (Too bad the NEC 8080-mode isn't really a Z80 mode.) In terms of price/performance, the V-30 gives alot of bang for the buck; cost was about $21. /kim -- UUCP: {decvax,ucbvax,ihnp4}!decwrl!mips!kim DDD: 408-720-1700 x231 USPS: MIPS Computer Systems Inc, 930 E.
