  Buy? Who said anything about buying??? I can get all the drives that I
want for next to nothing. If I do pay for a PC, it's only about $1 each.
FWIW The REAL QD 80 track drives and disks are starting to become scarce
so I've started picking them up when I find them.

   I have docs for the Mitsubishi 4853 (that's what I use).

   I have an old PC that I picked up from a trash pile that I use for disk
copying/transfers/etc. I've installed a CompatiCard and about six different
drives in. (Total cost so far: $4.00 for the CompatiCard) I haven't put an
80 track (80 cylinder!) drive in it yet since I haven't needed one but I've
got two perfectly fine 4853s laying here and looking for a cause.

>that _will_ write DSQD disks perfectly well.

   That hasn't been my experience. Most of the times that I use a 1.2M
drive to read/write other formats, it fails. Even when it doesn't fail the
copies don't hold up well. I could NEVER read my SB 180 disks (QD) in a 1.2
Mb drive. In fact, I finally pulled the 1.2 Mb drive out of my main PC and
put a 360k drive back into it since the 5 1/4" drive was used almost
entirely for reading/writing old disks.
