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. -michael ******** Note new website URL ******** NadaNet and AppleCrate II for Apple II parallel computing!
