There's no handy way of connecting a selector switch. no changed all Try connecting directly to the 10-pin connector on the left side of the MXV11, start it up, and hit the HALT button. You should get an address and an ODT prompt. You should get another prompt every time you press RUN, if HALT is still pressed in. Assuming the panel is connected to the backplane correctly. The MXV11-B only supports 300/1200/9600/38400 baud. J9,J10,J11 control the setting for SLU0, J7,J8,J9 control SLU1 (the console port). 9600 is J9 to J10, and J8 to J9. J61 to J62 forces SLU1 to be the console. It's also possible that you have some kind of custom bootstrap in it. MXV11-Bs were sometimes sold without boot ROMs (the standrd ROM set is known as the B2 ROM set, and marked as such), and use the same software arrangement as the MRV11-D ROM board, so people were able to roll their own using information in the MRV11-D manual. -- Pete Peter Turnbull Dept. of Computer Science University of York
