I don't think it will make much difference but the two Texas 28-pin chips to the left of the disc controller are the speech upgrade chips, so they can be removed for testing purposes as they are not essential.
Those 40-pin sockets with no support bar in the middle are slightly unusual I think.
Has the 1MHz bus connector been removed, or was it never there? Maybe check for shorts if it has been desoldered.
