Was the ancestor of SCSI, the SASI protocol, nothing more than a draft?

I recently discovered that the SCSI protocol was, in fact, an improvement on the SASI protocol, which apparently predates SCSI by only a couple of years, appearing in 1978 (but only publicly in 1981). It was only shortly after, in 1982, that the…

Is the maximum voltage of high voltage differential SCSI documented somewhere? All I can find in various source like Wikipedia is that it is "greater than 5 volts" ... but how high can it actually be? I have seen what HVD can do to a single ended…
