I have one of the 2216's and the original owners manual (in poor condition) and would love to find a service manual (electronic preferred).
If there are any updates on this thread it would be appreciated.
Also I have the rack mount 'ears' but the 'inserts' that go into the side 'holes' that hold the scope into the brackets are missing.
Does anyone have pictures or source of these little guys?
Looks like there are four per bracket.
Thanks for any tidbits on this nice 'digitizing' analog scope :)
