[comp.sys.next] Speaking of 105 meg disk drives

jtn@ADS.COM (John T. Nelson) (01/19/91)

Hmmmmmm speaking of that 105 meg hard disk, does anyone know if it can
be de-installed fromt he NeXT and then re-installed in a Macinotsh and
would it work?  The 105 megger is inadequate for a Unix environment
but one could salvage it by putting it on a Mac and buying a cheaper
third-party BIG disk drive...

or is this heresy?

Seriously.  Any incompatibility problems between this drive and Macs?
Can a Mac use a drive not specifically tailored for it?  I'm also
thinking that maybe third-party chips might be less expensive than
NeXT sells them.  Those are special interleaved 4x4 meg SIMMS though
aren't they... expensive.

And while we're on this subject.... that Megapixel colour display for
the NeXTDimension is pretty expensive for a Trinitron monitor isn't
it?  $3,995.  I wonder if one could connect NeXTDimension to a
third-party alternative or even one of those direct video tee-vee sets
that are being sold.

I don't see why it shouldn't.  I took the 40MB swap out of mine
and am using it on my Macintosh.  The drive may or may not format
depending on the software you have available.  Third-party
software shouldn't have any problems (i.e. SilverLining).

As long as the drivers are correct and the drive in question
conforms to Apple's SCSI spec, all should be well.

Those who wish to do the opposite (make a SCSI disk that was
_working_ on a Mac work on a NeXT) should be aware that some Mac
disk software--SilverLining, for instance--set some drives'
software SCSI ID flag.  What results is you can't change the
drive's target address via the jumper switches without resetting
that bit--a most frustrating experience.
