DIY disk upgrades for 760?

[phr@netcom.com (Paul Rubin)]

I confirmed with IBM Direct that the hard disk cartridges for
the 760 are incompatible with the 755 :-(.  It's probably too
early for anyone to know if it's possible to replace the drive
inside the 760 cartridge the way it's possible with the 755
(I mean using an OEM drive), but this seems like a question worth
keeping in mind, and if anyone does find out the answer please
notify the list.

PS, some pricing info: before the announcement, some mail order
place (I forget which) was quoting the following for Oct. delivery:

   Model	TFT size	disk		price $
   760C		12.1"		720MB		6329
   760C		10.4"		720		5649
   760CD	12.1"		1.2GB		7719

Yesterday, IBM Direct quoted me the following:

   760C		12.1"		720		6049
   760CD	12.1"		1.2G		7449
   760C		10.4"		720		not available yet

The similar price ratios for the 12.1" models suggests that the 10.4"
760C will be around $5427 from IBM Direct (found using the ratios for
the sums of prices of the other 2 models).  Since mail order discount
tends to beat IBM Direct by 5% or so, this suggests a street price of
around $5156 for 760 8/720 with 10.4" svga, compared to the current
price of around $5K for a 755CX/810 with a similar screen.  This is
quite attractive since the 760 sounds like a nicer machine all around.
The one scary thing is the prospect of getting clobbered for disk and
memory upgrades (the latter at least til an aftermarket develops).
