68kMLA Classic Interface

I've been comparing my orange micro card and your schematic and found a couple of show stoppers as well as some other corrections.

I don't know what value the caps I haven't scribbled on should be, but I feel some of them are too small. I'll come back to that. I might need to dismantle the orange micro card, which I'd rather not. It is the only OPTi card I've found (it's a nice dual FW+USB card, made for macs).

Suggestions (red is certain, blue is... theory/guess) :

Your 10k resistors at R43 and R50 are attenuating the USB data lines. The signals can't get through.

It will help you work out what the caps and inductors are.

The caps I can see what values they are with my multimeter.
The inductors... does it matter that much?

Can I see a current photo of your personality card?

I'm going to struggle to get much more without dismantling a card. I wish I had a card like @Fizzbinn's - it's very similar to the design we're heading towards. I can see the 15k pull downs and 33R inline resistors.

anyone got a way to read OrCAD 9 files? opti's website has an application schematic of an example board (http://www.opti-inc.com/html/usb1394.html or attached below).

I'm paying attention! 🙂

We need to populate one of these to get 3.3V, if one isn't already populated??

Couple more caps worked out here :
