As I recall you were having problems with an HPIB disk on a faster 68040
cpu?  We have run the HPIB related drivers in our 4.3 and 4.4 on 30-40
machines for 7 years now, but only with 68020/30 machines.  In fact we did
have a hanging problem with the 50mhz 030s and some disks that I hacked
around, but that hack was in even the net2 code.  Come to think of it, we
are actually using some HPIB disks (7937H, 7959B, 2200) on a 25mb 68040
with no problem.

A couple of possibilities:

1. The DELAY macro may be off, its a crock.  You may have to increase
   cpuspeed.

2. You are trying to use a SCSI interface and the 98625A HP-IB interface.
   You must have a 98625B if you also have a SCSI.  If you are using the
   internal slow HP-IB (at sc7) everything should be ok.
