ADF Adapter Description File

Three versions of the ADF are listed, exposing certain differences. The ADF versions have been obtained from the EPRM collection and Model 70/80 Reference Disk, versions 1.12 and 1.06. If you experience problems with the ADF version you have chosen to use, you may try the other two ADFs. Rename @DF9F_0.ADF or @DF9F_1.ADF to @DF9F.ADF prior to using it.

@DF9F_1.ADF, supplied with the Model 70/80 Reference Disk V1.06 (1988, German retail version) does not contain the DMA Pacing Control and Time to Release settings. The primary port address is assigned with a fixed resource setting and the bit-3 setting of pos[1] is not found in the later ADF versions:

@DF9F_1.ADF, Mod. 70/80 Reference Disk V1.06 (1988)

   FixedResources
      pos[1]=00XX1XXXb
      pos[0]=XXXXXX0Xb
      io 3510h-3517h
      int 0eh

The ADF featured in the EPRM ADF-1 Collection (EPRADF1.INF) differs from the ADF supplied with the Model 70/80 Reference Disk V1.12, and also found in the EPRM ADF-0 Collection (EPRADF0.INF), in the bit patterns of the DMA Pacing Control and Time to Release settings of pos[2]:
