Of course, at this time I can't say if the voltages or signals are correct,
but the form-factors do seem to match up; they're plug-compatible, in any
case.
They probably are; it seemed weird that Osborne went with the non-standard
drives for the Osborne 1 - I'm not sure what the benefit was supposed to
be. Sure, they probably saved a buck on a power harness, but I don't know
if that negates the hassle of getting custom drive units made.
Seems like the best route is to hang out 'till
someone with a working
Osborne offers to send me some bootable media.
Well if it comes to it I'm sure we can figure out something when the OCC1 I
have finds its way to you. But I expect that the Vixen uses DD by default
though, doesn't it? In which case - if the Vixen drives aren't anything
weird - you should be able to hook one up to a PC and write some media; any
old PC FDC should handle it.
Thing is, I don't think I
even have a User's Guide for this thing - isn't there some sort of ROM
monitor you can invoke from the boot screen? Maybe not, but it seems like
something that ought to be there..
I really don't know about the Vixen - I don't think the OCC1 has anything
like that though, it's pretty basic.
