Thank you, Ben. Looks like my Matrix-12 has the latest firmware all around, so I won=E2=80= =99t be opening it up. Thus, I=E2=80=99m still looking for a complete set of Main Processor = Board ROM files. I already have all the files needed to upgrade my friend=E2=80=99s = Xpander to the latest - if we can find an EPROM burner. I have an EPROM = eraser somewhere around here=E2=80=A6 Brian On Nov 6, 2018, at 5:05 PM, codemechanic <xxxxxxxxxxxx@xxxxx.xxx> wrote: > I would add that Xpansions issue 8 from 1991 confirms the latest > software versions found on sequencer.de: >=20 > Xpander > Main Processor: 1.2 > Voice: 1.4 > Cassette: 1.0 >=20 > Matrix 12 > Main Processor: 1.1 > Voice: 1.6 > Cassette: 1.0 >=20 > -Ben > On Wed, Nov 7, 2018 at 8:35 AM codemechanic <xxxxxxxxxxxx@xxxxx.xxx> = wrote: >>=20 >> Hi Brian, >>=20 >> I own an Xpander which I believe has v1.2 Main board ROMs and v1.4 >> Voice board ROMs, but unfortunately I can't confirm that as I'm out = of >> the country at the moment. >>=20 >> In searching around it seems like there's more information out there >> on the Xpander than there is on the Matrix 12.
