From what I remember, the earlier vulcans (non-gold) had the drive
specs size, cyl, heads, etc hard coded into the ROMs. So unless you
can find those original (Western Digital - i think) 20 and 40 meg
mechanisms in working order, you're going to be hard pressed to get an
older vulcan controller to work with anything else without a gold rom
upgrade.
Which is why I was hoping a comparison of, say, the //e 20MB ROM
with the //e 40MB ROM might point the way to creating a new ROM
with support for a particular drive--or even generalizing the
drive support to some degree.
Of course, we already have more general IDE controllers, so
maybe rescuing Vulcan controllers isn't useful.
