In article <05.02.92.140430.195@cogsci.cog.jhu.edu>, I requested
information about installing a Quantum ProDrive 105 (SUN104) SCSI disk drive
in a SparcStation 2 which already had a SUN207 drive installed. I received
very helpful information from the following people.
Ric Anderson
Daeshik Kim
Brian Zavatsky
Karl A. Nyberg
Robin Friedrich
Richard Nickle
Mike Slade
Robert Duckworth
Jay Berkenbilt
Henry Bryant
The basic answer was yes this will work and it is even supported. I
will summarize their responses below.

Some comments about Sparcstation 2 compatibility:
Ric Anderson:
>SS1's can't handle any drive bigger than the Pro-Drive 105
>and they can only have two of those. SS2's can handle two 200mb
>drives (or a 200 and a 105) OK according to my Sun FE as of
>last April when I asked him.
Brian Zavatsky:
>... The 105(104) will slide right into your SS2 without any power supply
>problems, or heat related problems and is a fully supported configuration.
>...
Robin Friedrich:
>... From my experience the power supply should be capable of driving
>everything you have attached. ...
The best description of the drive itself follows. I added some information
pulled out of other people's notes to make it more SUN relevant.

And some possible problems:
Mike Slade:

Robert Duckworth:
>... All I know about this drive is that earlier models tended to 'stick'
