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

Voice Board ROM data as well.
