I am writing to request some information on the video settings for a Computer Dynamics 386 SBC-SXE motherboard.
I have just replaced a legacy system which interfaces to a EL7768MS display board. I can see the display via the standard VGA output to a monitor, but I can't get a display on the EL7768MS display board. I understand that this old series of 386 SBC can be set for simultaneous video display mode but without the manual or information on the 386 SBC-SXE motherboard, I don't know how to set it.
Will greatly appreciate if anyone who has the manual can assist to advise which jumpers to set to achieve the desired result.
