I had a problem with a Wangtek 5150ES SCSI not streaming.  It turned out
that there's a jumper that selects "power-on buffered mode" which was in
the wrong position.

In trying to track down this problem and get jumper diagrams, I discovered
that Wangtek has at least 3 revs of the (SCSI) circuit board released.
In my case (this may not help you all, since you're using a PC-36), HDR3
PIN 7 needs to be set in the A-B position.  This is for board assy #30600.
For board assys #33671 and #30559, its HDR3, PIN 1.

I hope this is of some value to you and others...
