Elektronika MK-61 - today I ordered one NIB

[Hans-Peter]

Mine is just finished, with the TZ-tape. I only wait for the grey tape to make it perfect on the keys.
Between the keys is a printed self adhesive plasic paper.
The Manual is a little bit thin and I'm looking for some more hints.

The battery compartment had plenty of rust but after some cleaning, the calc works fine.
