They (the LVD ones) show up from time to time, but tend to be
rather expensive most of the time.

I found mine at a hamfest for about $35.00 IIRC. (Sorry, I
can't remember the number -- it is too new to be in my FEH (Field
Engineer's Handbook).

But -- can't you use a SE one instead? Almost all LVD drives
will talk to a SE controller and vice versa -- just with the restriction
that if you have a SE device or controller on the bus, it will talk to
*everything* as SE instead of LVD. Since you want to talk to a drive
inside your computer (IIRC), the length of the cable certainly does not
call for LVD.

The only LVD device which I know of which will not work properly
on a SE bus is the Exabyte Mammoth-2 tape drive. If the drive says LVD,
it *needs* LVD. Even the jukebox which it was in (an EXB-430) would
communicate nicely with a SE controller, but the drives would not.

Enjoy,
DoN.
