What about the 2 MHz U42 oscillator? Thanks! - Alex On Sat, Jun 28, 2014 at 10:19 AM, J. Alexander Jacocks <[email protected]> wrote: 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! - Alex On Wed, Jun 25, 2014 at 1:18 PM, J.
