I have a nasty suspicion that if the machine has already been used, the 
Primary Boot Loader will have been updated to 5.1 (the machines were 
generally sold with 4.9 installed, but connecting them to a phone line 
prompts an automatic update).

See http://www.earth.li/~noodles/hardware-e3.html for the comment you don't 
want to read: "Note that only PBL 4.9 will work at present; PBL 5.1 is known 
to have made changes preventing this mode from being entered. If you allow 
your E3 to receive updates from Amstrad then it's highly likely it will be 
upgraded to PBL 5.1"

I don't know how to find out the PBL version from the machine itself (unless 
it's unused, when you can press Setup on the pull-out keyboard as described 
at http://inputplus.co.uk/ralph/emailer/e3.html - unfortunately yours is 
clearly used), except by connecting a serial cable and talking to it.

That's not hard, though - see http://inputplus.co.uk/ralph/emailer/pbl.html

Hope this helps,
