Here are some more details: The Matrix-12 Processor Board has five 8KB ROMs The Xpander Processor Board has four 8KB ROMs Voice Boards have two 8KB ROMs, and appear to be universal for Xpander & = Matrix-12 (not confirmed). I have an incomplete set of Matrix-12 Processor Board v1.2 ROMs, (0, 1, = 4), and I need the two missing ROMs (2, 3). I am still looking for a complete set of M12 PB v1.1 ROMs, but I might = just buy a ROM reader and pull the chips from my Matrix-12. My Matrix-12 has v1.6 on the Voice Boards. Meanwhile, I recall a resource that listed the latest ROM versions for = both Xpander and Matrix-12, for both Main and Voice firmware. Can anyone = point 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 = them is valid. >=20 > I=E2=80=99m looking for Matrix-12 ROM files. At the very least, I = would like the Processor Board ROM data. It would be nice to have the = Voice Board ROM data as well. >=20 > I=E2=80=99m working on a patch librarian for macOS, and need the ROM = data to scan for undocumented MIDI System Exclusive details.
