it worked .... i jumped the usb cable from just behind the display 9 pin usb
to my desktop computer and it seems to work well ... now running the radio part of the mb1 with an i9-11900 computer
.... i did try an asus mini atx mainboard swap in the mb1 but the mb1 only provided 12 volts to the power connector .... all other connectors seemed to be ok but couldnt get the board to post at this time receive is working but no tx

mdh11hi motherboard download.gigabyte.com/FileList/Manual/embedded_mb_qsg_mdh11hi_e_10.pdf?v=a4c6c702dec7b181515ca6e5985e0afc I will post pictures later today
i jumped the cables that were hooked up to #16 and #31 from the mb1 to the decktop computer with usb header extender cables , i installed the sdr3 software on the desktop.then configured the new network from the usb to ethernet adaptor to the correct settings found in the online manual , the mb1 is powered but just shows a windows screen , the desktop monitor displays the sdr3 program
, i have found that all the buttons on the mb1 still function , my next experiment is to buy some usb header to usb cables and see if i can run this setup on a mac .... will post results

I have been running the mb1 by jumping the header cables to my desktop.... so far so good , no need to update the mainboard in the mb1 ,most of us use the mouse keys and external monitor.
