Anyone have Shugart 460VR / SA460 docs? Is a 460VR
the same thing as
a SA460? The drive in my Intel iPDS says Model No. 460VR. Could it
be functionally replaced by an original IBM PC full height 5.25 drive?
The drive from the iPDS has jumpers on both DS1 and DS4 installed. I
wonder why that is?
I don't know what the "VR" means, but an SA460 is a 80 track (96tpi)
drive - you won't be able to replace it with a PC 48 tpi drive (normally
a SA-450 or TM-100-2) - you will need something like an SA-450 or a
TM-100-4 (both full height), or Teac FD-55F (1/2 height).
These drives can be tougher to find than 48 tpi drives - If you don't
turn one up you can modify many PC/AT HD drives to opperate as an 80
track DD drive - you need to switch the speed to 300rpm (I've got info
on my site about doing this), and make sure the density select is tied
off for "low density".
