I was wondering if anyone had an idea about an 11/23+ I picked up recently. It's a normal looking 11/23+, but the UART closest to the console connecters is replaced by a 40 pin socket. The socket has a ribbon cable attached which goes to a small board (2x3.5 inches) that contains a UART and a couple of other chips (notebly a dallas ds2010). Looking at the socket, it's not a rework, I believe the board came this way from DEC. The small board has a part number 010-01135-00 rev b etched on it. Thanks, Bill King
