Try a new cable. Try a second drive, if you have one with the Super 
Controller. Try the current drive with a standard controller or with a 
PC. It won't take long to tell what is bad.

The MEB connector acts much like an MPI. Tony created several add-on 
boards that plugged onto the connector, Real-Time Clock plus Parallel 
Printer Port, EPROM programmer (I own one), and a Hard Disk adapter.
