I have a microExplorer system with one internal and
two external Apple 80MB hard disks.  The machine occasionally
gets into a "hung" state when opening or closing a file.
It usually, but not always, happens when doing a lot of
consecutive file operations, as in a make-system.

The symptoms:

1. The status line says "open" or "close," and there is no
   disk activity or run bar activity.

2. I can get the machine back by aborting the access, but no
   subsequent access works.  (Always hangs in the "open"
   state.)

3. A warm boot gets things working again.

I wondered if there was a problem with the SCSI termination, 
but I've tried placing the terminator at different points in
the change with no noticeable effect.

Also, the last time this happened, I was able to access the
same disk and files from the Mac with no problem.

I'm running system 6.15 with microcode 138.

...Greg
