Just one question. Looking at adapter cables from other units, it doesn’t seem like the cable connects to anything other than the card to the DB15 connector. So to toggle between GND and VCC for PIN 11, where do I get VCC from?
The frequency select signal is pulled high on the card itself through RN10, so you'll only have to connect it to GND or leave it open to select between the two oscillators.
Just for a status update. I've modded the back panel of my Mac SE/30 to accomodate a switch and DB15. I've wired up the DB15 and awaiting the arrival of a connector for the XCEED card. I'm going forward with the advice above for wiring.
Just for clarity, you said pin 12 (CableOK) should go to ground. Does that mean I put a jumper between pin 12 and pin 3 which is supposed to be GND?
