Re: Vulcan HD Breakthru
That's great news.
I'm with Wayne, I'd love to get a 100-200megger going, I have a 170Mb Conner
that is worth a go later, and for starters I have a Conner 40M CP3000 model
that was used in these things, so this is definately worth a go.
Is you Vulcan a //e model or a IIGS model ?

The
