Can't speak for it being an SMD

I was always thought that the R80 had to be unit #0 to function, but I admit

drive(s) on

The R80 started out life as the disk for the ill-fated

Well, actually I think you own an R80 but don't know it :-)
As I understand

I think you should sacrifice the RA80 for a working R80. I know there
are several RA80 in the wild but I've never heard of a R80.

Well, considering the main bits
You're invariably gonna take up more space with all the removed parts after
