Amiga OS 4.0 and 4.1 Final Edition for Classic

[tlgrooms]

I bought Amiga OS 4.0 back in 1987 for my 3000T with Cyberstorm PPC card.  When I tried to install my hardware quit working so I was unable to ever install it.  I see now they have 4.1 Final Edition for Classic and was wondering if I need to rebuy the OS to get 4.1 or if it is available as upgrades to 4.0?  I am getting ready to reload my working machine.

Thanks for any info.

Man, I don't know where I came up with 1987?  That should have said 2007.  Ha!  Only 20 years difference.

Ok, that's what I'll do, thanks for the info.

I was just about to ask that kolla.  Did you have trouble installing it?  I have a SCSI2SD board I'm thinking about trying to set it up on with the Cyberstorm.  I wonder if that would be slower access than if I used an UWide drive?  I have a 4.3 gig ultrawide drive.
