Thanks for the info.

I apologize for wasting your time by not doing a through search before I posted. I should have done so. What I meant by not A7, S7 or Z7 is that it is not of the current generation of boards that are called the Arty A7, Arty S7, or Arty Z7. It is just called Arty, and has an A7 FPGA. Thanks for your "historical context". It's downright bizarre paranoid behavior on Digilent's part.

I have an original Arty board that I purchased years ago and never did anything with. I'm about to do so now but discovered that the schematic I have, and the one available on the web page for the original Arty (not A7, S7 or Z7) does not show the USB port or FT2232 chip and all the associated components and nets. The schematic I have is C.1. What would be sheet 10 is blank except for "This Page Intentionally Left Blank". In the Bookmarks sidebar there is a Sheet 10, with a subheading Components, under which are a bunch of refdes numbers including IC8, which is the FTDI chip on my board. This leads to the conclusion that sheet 10 used to show the USB components but that they have been removed. I also have schematic C.0 which has the same issue. The reference manual downloaded from the same page, and having an approximately 2 year newer date, talks about the USB port and USB chip to a significant extent. My board has a sticker with D754100, and printed on the board is PB200-319 Rev C So the questions are: Why are they missing from the schematic? Is there a version of the schematic that shows these parts?
