Oh, and I assume that, for 10 MHz operation, U46 needs to be changed to 10 MHz? What about the 2 MHz U42 oscillator?

Thanks!

I was just doing up a BoM for the V2 CPU board, and I noticed a few discrepancies between the parts list, from s100computers.com, and the description, on the page, and the board layout picture.

First, there is one IC that should be a 74F, there is a missing 47 uF cap, and the IC count is 39, from the parts list, and 44, on the board. There are also a couple of missing LEDs, in the parts list.

Is the board picture more current, or the parts list? Given that the parts list is a bit internally inconsistent, I assume that it is the board layout picture.

Thanks!
