The regular S1 tape exists in a few places, yes use L to load tape. This is the best practice. Purely as an experiment I made a monitor script so I could run at a slow speed so I could watch the screen as commands were entered. I can't remember if it was because the load (L) was not working or if there was a cpu card issue. I thought as a first step, given at the time in the flow of the thread the OP was having issues, my monitor script would be worth trying. Bill
