I encountered the same problem with my Micropolis 1375 - the guys at BMS were
very helpful in diagnosing the problem, a new PROM from Micropolis (no charge)
solved the problem.  Seems that Macs exhibit the same characteristic, but if
I understood properly it could be easily solved if TOS were to do a SCSI reset
prior to attempted booting.  Perhaps a floppy boot sector program could be
written to do this?  Wouldn't add any time, since the boot sector always gets
read anyway...
