However, the behavior of trying to load smth from a tape, reminds me of the autostart facility of the I/O ROM of the 9825 (9825 I/O ROM manual, page 4-3): Quote: The I/O ROM is normally not present in an 9825A unless the appropriate drawer is in place. However, if the 9825A has been upgraded, it may contain built-in ROMs. This should be indicated in the inside cover of the printer paper bin.
