Can some kind soul point me to the technical documentation for the Q-Bus DLV11 M7940 Serial Line Unit? It has a 2x20 pin-out connector of unknown. I gather that it's a pretty common card, so I'd expect the documentation to still be "out there" ... like the truth :->. Not the DLV11-J, which is the 4-line card. The only good news is that the MC1488 and MC1489 are nearby, which will help a little. But documentation is *much* better! Probably any of its variants will do just fine (e.g., M7940-YA "M7940 W EXTRA WIRES TO BRING OUT CLOCK & 110/300 SPEED CHG"). Attached is what I've thus-far been able to find, which is jumper-info dug out of a paper-tape reader manual! Thank you, paul
