Hi, Any TRS 80 gurus that can point me in the right direction with the disk/video interface box? I recently picked one up and have it connected to my model 100. Everything appears to be working, but when I start the interface box, it requests a system disk. Is this required to use the interface box, or is there a way to go right to the mode to display 80 columns and skip the boot disk in the interface box? I have the owner's manual, unfortunately the disk is missing and it appears the disk is required to get the interface box to do anything? Any pointers where I might find the software? Thanks, Win
