I have a PDP11/53, which on inspection contains 2x M7651:
- One cabled to a same-sized card made by Logica and marked 3490/300
- One cabled to a double-sized card marked 3350/304 (assuming Logica)
Both these cards appear to be SCSI controllers, but does anyone know any
more about them? And I'm wondering if there might be some hoops to jump
through in their use, E.g. only support certain drives or require a patched
Looks like one of these M7651/SCSI controller pairs is going to have to go,
in order to make room for ethernet...
