According to the manual, there *is* an address selector on each E20S
(or E40S, etc), but all it says is
11. Setting up hard disc units
If there is more than one hard disc connected to a Filestore, you must
set the drive numbers and titles to avoid clashes, as follows.
11.1 Setting the drive number
The drive number is set by a switch at the rear of each drive unit.
Set this to a different number for each hard disk unit, while
Filestore is switched off.
11.2 Setting drive titles
[describes how to start Filestore in maintenance mode and use
There's no diagram, unfortunately. I do know you can have a maximum of
four hard drive units, so it's probably a small switch; maybe a
two-pole DIL switch. My service manual is only for the earlier
E01/E20, not the stacking versions, so that's no help either.
