Good morning everyone,
A sincere
thank you if you are willing to spend time on my question. You're great.
My idea is to replace the FDD drive on my Agilent 54621A. I made a teardown video (unluckily only in Italian, by now):
I did some reverse engineering on the main board and on the FDD drive, the results are in the picture below:
I would like to use an FDD-to-USB converter like this:
MY PROBLEM:
I believe that I can get a way with a simple adapter between the FFC cable and the classic ribbon cable, the question is: which is the pinout of the proprietary Agilent FFC?
I searched the web from North to South, with no results.
So I thought of finding out by my own, analyzing the pinouts of the controllers. I already have the datasheet of the PC87338VJG, but it's pretty messy to reconstruct the connection between it and the connector.
It would be A LOT easier if I could retrieve the pinout of the NN8863FAW, since the pins are directly connected to the FFC connector on the FDD drive. Really, the connector is about 5 mm from the chip, and the tracks go straight.
Unluckily, I could not retrieve any datasheet of this IC, nor even a pinout.
Does anybody have a link, an idea, a suggestion?
Thanks again for your time.
