1 CMS 9609 MPU board (6809, 2 6821's, 2 6850's,
3 2716 EPROM's, one marked
"Debug 09", others unlabeled)
I wonder if that might be a Motorola MICRObug Monitor/Debug, or a copy
of it? Motorola sold it both on a board and as an individual ROM. I'd try
to read it with an EPROM burner and dump the code and see if you can find
any copyrights, help instructions and/or commands.
