OK, I saw what part of my issue was. I had the CRU for the TIPI above the HFDC, rather than at >1000 because previously I had the Myarc 512K card in the system. It is not in the system now.
With the Myarc HFDC in the system, I tried with and without DSKx device mappings, with and without Auto Mapping, and TI/Myarc WDS settings. Trying to copy DSK1 attempted to go to WDS1.DSK1. and could never get a copy to real DSK1. Trying to copy to DSK2 (real) resulted in the drive light coming on, but an "Error 0:"
Separately, on an earlier attempt knowing I had three mapped DSKx. devices specified in the TIPI.CFG program, I attempted to copy files from DSK1. to DSK4. thinking/hoping the files would copy to the HFDC floppy drive 1. Surprisingly, those files instead copy to the TIPI root path.
I do not know if there is something unique about the Myarc HFDC versus the TI controller, but I am not able to copy files as Matt indicated earlier.
For Matt's information, copying from DSK1 to DSK4 as noted above, I thought I recalled Matt adding the extra DSK4 mapping??? Maybe there is another CFG program I need to update to map it????
