Konan "Blue Sky" MFM Controller - Looking for documentation

[Mal]

I have a Konan MFM controller that I am trying to find documentation for.

This was part of a large SD Systems 600 all-in-one S-100 system. The controller consists of a daughter-board that plugs into the Z-80 socket on the S-100 CPU board, and an external double-sided blue PCB that includes a large Konan LSI chip. The controller was connected to a Disctron D-507 5MB MFM hard drive.

The daughter board has "Blue Sky" marked on the underside of it. There does not appear to be any other model numbers on either PCB (other than obscure PCB numbers).

If you have any manuals or software for this board, please let me know.

My best guess is that you have a Konan David Junior II board (DJ2) which connects to the host with an 8-bit parallel port (perhaps what the Blue Sky board implements). documentation here: http://bitsavers.informatik.uni-stuttgart.de/pdf/konan/Konan_David_Junior_II_Reference_Aug83.pdf

Thanks for the tip. My board is smaller than the DJ2 board, and has a much lower chip count. Perhaps it will be software/command compatible with the DJ2 board though. I'll check that out.
