Can anyone po= int me to that? I have a friend who is interested in upgrading his Xpander = to the latest, if we can find out what the latest is. I=E2=80=99ll probably= update my Matrix-12, too, since Main PB v1.1 seems to be old. > > > > I have a complete set of Xpander Processor Board v1.2 ROMs > > I have a complete set of Voice Board v1.4 ROMs > > I have a complete set of Voice Board v1.6 ROMs > > > > Brian Willoughby > > > > > > On Nov 4, 2018, at 5:56 PM, Brian Willoughby <xxxxxx@xxxxxxxxxxxx.xxx> = wrote: > > > I have several copies of the Xpander ROM files, and at least one of t= hem is valid. > > > > > > I=E2=80=99m looking for Matrix-12 ROM files.
