SMB - System Monitor Board contains 1k EPROM in a 2708 typically containing Zapple monitor. Also 2k RAM. 2 serial ports rs232 or current loop, 1 parellel port.
Note: The ribbon cable connecting to the "Interface One" daughter board containing DB25s spaced to install in a Imsai rear panel. I haven't seen this board previously. I'd like to find some documentation for it for the record. Use the contact form if you have the docs.
