GetDevBlocks and PutDevBlocks read (GetDevblocks) resp.  write data
from/to any trackdisk-compatible disk, e.g.  DFx, RAD, HD0 etc.  I
coded these tools in 1993, but it seems I never uploaded them zo
Aminet.  They were predecessors of PackDev, a very flexible disk
device packer with XPK support.  Now as there is something like UAE
(Unusable Amiga Emulator) there seems to be a use of at least
GetDevBlocks, since UAE uses file disks for floppy disks.  The usage
is as follows:

GetDevBlocks <Device> <StartCyl> <StartBlock> <StartHead> <NumBlocks>
    <File> [LAB] [DUMP]
PutDevBlocks <Device> <StartCyl> <StartBlock> <StartHead> <NumBlocks>
    <File> [LAB] [DUMP] [FORMAT]


LAB     Read/write label buffer data from/to <File>.lab
DUMP    Treat <File> as a hex dump (like "type OPT H")
FORMAT  Format tracks before writing to (label buffer handling
        may fail for device-internal reasons)
<File>="*" for GetDevBlocks: Send data to output stream (not to *)

To get a complete disk image (880k) for UAE, type

  GetDevblocks DF0 0 0 0 1760 foo

and the file "foo" will contain the disk image.

GetDevBlocks and PutDevBlocks are freely distributable, as long as no
payment greater than $5 per floppy disk or $50 per CD is charged
Modifying or removing any file of this archive (i.e.  GetDevBlocks,
PutDevBlocks and DevBlocks.readme) is not allowed.   Use at own
risk. Commercial
programs (including shareware) using them in any way need a written
permission from me.  A certain payment is expected, which will
typically be a fully registered version of it.
Have fun with them.

Compatibilty: Runs fine on my A4000/060 and ran fine on my old
              A400/030

P.S.: Don't expect any future versions from these programs. And no, I
will not give away the source code.
