Bulk call tester

Hi,

does somebody here on the list has access to a Ameritec AM2-DE E1 bulk call
tester or the firmware files for it ?
Ameritec does not support this anymore - the support states that they donot
have access to these files.
On my device the battery died, an so all files are gone and I have no
diskette.

It should be easy to get these files from a device, here is a backup
procedure (I can provide the manual).

Thanks in advance
Karsten
