No other board.  Your suffering from PCism, you expect it to work like 
a PC and it will not.  

I'm using a 45MB fujitsu 3.5" scsi drive That was given to me and a 
modified version of the ampro scsi bios.  The base SCSI software 
supports a limited number of drives and SCSI to MFM bridges that were
available in the mid to late 80s.  Those would be the Xebec and Adaptec
and one seagate drive all in the 10-30mb size range.

Add to that at the time the AmproLB+ software was written SCSI nee SASI
was still somewhat developmental.

Yes, I had to take the Ampro sources and rework them a bit for that drive 
and debug them.  The basic code is online in one of the repository sites
and it's well done so modifying it should be resonable. I'll admit it's 
been 17 years since I did it and it's running so I haven't looked at it in
a long while.  


Hope that helps.
