Matti,
I used the LHWARP utility , it is an exact copy (albeit compressed) of the
original disk. The LHWARP used is the later version of two on Fish 318.
To deLHWarp the archive, place a blank disk in df0: and use
lhwarp Write 0 ham1
^use 0 for df0:
1 df1:
2 df2:
3 df3:
This should recreate an exact copy of the original disk track by track.
Cheers, John.
