The cheapest and simplest type of SCSI bus, where all the return lines
for all the signals are simply connected to the same ground. Also
sometimes called `normal' SCSI, as most of the controllers and drives
out there are of this type.

As distinct from LVD (Low Voltage Differential) and HVD (High Voltage
Differential, also known simply as `differential'), where each signal's
return line is driven to the opposite polarity to the signal itself.
