I cloned John's database entry and edited it to make Mayank's database
record. I must have missed updating the email address. Fixed now:
"Mr. Mayank R. Patel V Seagate Technology patel at cdg.seagate.com"

I've added your 'key statement' to the minutes as follows:
"Gene Milligan closed the discussion by noting that all the discussion
seems to be directed at the fact the SPI-2 standard works well and that
since it is a forwarded draft standard why is the working group spending
more time on SPI-2? Gene also noted that it is hard to say you will not
get errors and difficult to say you will never get undetectable errors.
Gene concluded that everything points to the importance of adding CRC when
the transfer rates are increased further."

Changed to: "and none appeared to produce the problems that Bruce thought
would be fatal."

Both the change and the addition are included in rev 1:
"(called Fast 80ish in the presentation because Gene felt that some of the
described techniques might not be needed until Fast-160)"
"There was general agreement (no opposition) to removing HVD support from
SPI-3, except for noting the HVD voltage levels on the DIFFSENS signal."

Fixed as follows: "Ed said that he would not be applying for a patent.
The Quantum representatives said they were not aware of any patents or
patent applications but should any Quantum patent be required to implement
the standard, Quantum would license the patent at no cost."
Thanks for your comments!
