 I have several old disks which were formatted on the C1581 drive. I have
noted that when using RawCopy's trackread option and then selecting MFM
decode and IBM decode respectively, the tracks on the disk are decoded. 
Question: 
       1) I know about decoding MFM formats, but what is the IBM decode
algorithm?
       2) Do you have to bypass DOS in order to read a foriegn format?
       3) Amiga Disk Drives Inside & Out (Abacus) seems to use many
absolute addresses in its programming examples, why?

Thanx in advance (resp. by email is preferable but not necessary)

  Jeff M.
