[Coco] ORC 90 ERR 7

[coco at jechar.ca]

Cannot get anything saved from my ORC-90 to disk have tried both
my CoCoSDC which runs version DOS 1.6 and my SuperIDE interface which 
runs "DISK EXTENDED COLOR BASIC 2.1 / HDB-DOS 1.1D LBA"

I also have a floppy controller and floppy drives but for the past
five years I have only bin able to read floppys writing fails for
everything not just ORC-90.

In every case I get ERR 7 which the ORC-90 manual says is a i/o
ERROR.

Do I need to change a switch on the "Multipack" before saving?

Failing this is it possible to set up a raspberry pi to emulate
a coco tape player it seems that the default is to save to tape
but I don't have a coco tape player.
